refactor(stdlib): remove dotenv native binding

[proggeramlug]

Summary

Removes the native dotenv binding so import dotenv from "dotenv" (no
perry.compilePackages entry) resolves to the real npm package, compiled
from source, per the owner's decision to stop shipping hand-written Rust
reimplementations of npm packages.

The bug

dotenv.parse(Buffer) — the idiomatic dotenv.parse(fs.readFileSync(...))
— returned 0 keys, silently. dotenv.config() reported no error but
populated neither result.parsed nor process.env — a silent
total no-op. Any app that did the standard dotenv.config() at startup ran
with no configuration at all, no warning.

What was found and removed

Per #10678 (duplicate extern "C" exports across perry-ext-*/perry-stdlib
pairs), this binding existed twice:

• crates/perry-ext-dotenv/ — the governance-tracked binding crate, wired
  into well_known_bindings.toml's [bindings.dotenv].
• crates/perry-stdlib/src/dotenv.rs (104 lines) — a second, independent
  implementation behind the bundled-dotenv feature (default-on, part of
  full), exporting the same js_dotenv_config/js_dotenv_config_path/
  js_dotenv_parse symbols.

Removed both, plus every registry row: the 2-entry NativeModSig dispatch
block (config/parse) and its dedicated regression-test module in
native_table/utils_crypto.rs, the 3 js_dotenv_* FFI declarations in
runtime_decls/stdlib_ffi/utilities.rs, the well_known_bindings.toml
entry, the "dotenv"/"dotenv/config" NATIVE_MODULES entries and their
manifest rows, the bundled-dotenv stdlib feature (and its removal from
perry-stdlib's own full feature list), the 3 Android stub exports, and
"dotenv" from PERRY_NATIVE_EXTENSION_PACKAGES
(crates/perry/src/commands/compile/resolve.rs) — that array makes the
module walker skip a node_modules/dotenv/ tree entirely on the theory that
Perry's stdlib handles it natively; with the binding gone, dotenv's real
source (including the dotenv/config auto-load subpath) needs to reach the
walker like any other npm package.

Test-fixture edits, not deletions — six tests whose only failing
assertion was the now-removed registry entry, each updated to keep testing
its real subject:

• crates/perry/src/commands/compile/collect_modules/binding_faithfulness.rs's
  lookup_preserves_registered_subpaths_before_falling_back tested two
  subpath aliases in one function (mysql2/promise and dotenv/config) —
  kept the mysql2/promise half (mysql2 is untouched, out of scope), dropped
  the dotenv/config half.
• crates/perry/src/commands/compile/well_known.rs: dropped "dotenv" from
  shipped_unproven_bindings_are_partial's array (kept nanoid/uuid,
  each a separate PR in this campaign); deleted dotenv_is_registered
  (its entire subject was the now-removed [bindings.dotenv] entry);
  retargeted node_prefix_stripped_on_lookup from "dotenv" to "bcrypt"
  — that test exercises generic node:-prefix-stripping lookup logic, not
  dotenv-specific behavior, so it needed a still-registered example, not
  deletion.
• crates/perry-api-manifest/src/lib.rs's dotenv_parse_is_registered and
  crates/perry-codegen/src/lower_call/native_table/utils_crypto.rs's
  dotenv_parse_dispatches_to_native_impl_as_an_object — both regression
  guards for the exact manifest/dispatch rows deleted above — removed
  entirely (their subject no longer exists).
• crates/perry-hir/tests/unimplemented_api_check.rs (2 occurrences) and
  crates/perry-codegen/tests/manifest_consistency.rs (2 occurrences): each
  had a dotenv/config-only side-effect-only-module allowlist; trimmed to
  &[] now that no side-effect-only native module remains.

Left alone, deliberately: binding_needs_shared_tokio("dotenv") in
optimized_libs/tests.rs — this function is a hardcoded matches! list of
modules that do need shared tokio; anything else (including a name no
longer in the registry) still correctly returns false, so the assertion
doesn't depend on dotenv being registered. Also left alone: the real
dotenvy Rust crate used by crates/perry/src/commands/publish/mod.rs (an
unrelated Rust crate, not the npm binding) and
crates/perry-container-compose/src/yaml.rs's parse_dotenv (Perry's own
docker-compose YAML .env-file parser, unrelated to the npm package).

A standalone-workspace fixture the campaign's own registries can't see:
tests/release/packages/next-app-route/provider/stdlib/Cargo.toml has its
own perry-stdlib path dependency listing "bundled-dotenv" as an enabled
feature. This fixture has its own Cargo.lock and isn't a member of the
main workspace, so cargo check --workspace never touches it — found by a
repo-wide grep for the feature/crate names outside crates/.

Acceptance test: parse(Buffer) and config(), no compilePackages entry

{ "dependencies": { "dotenv": "^17.2.3" } }

An 18-key .env fixture (comments, quoted/single-quoted/multiline values,
inline # inside quotes, trailing whitespace, = with surrounding spaces,
empty values). Test does dotenv.parse(fs.readFileSync(".env.fixture"))
and dotenv.config({ path: ..., quiet: true }) (quiet: true suppresses
dotenv's own randomized startup-tip banner, which is nondeterministic
between runs and not part of what's under test).

Built on perrymaster (--profile perry-dev); compile log: Compile package wildcard: expanded to 1 installed package(s), 2 native modules (dotenv has
no transitive deps). Ran the binary and diffed against
node --experimental-strip-types (Node 26.5.1): byte-for-byte identical
— parse() returns all 18 keys, config() populates both result.parsed
and process.env with no error, matching Node exactly.

Verification

• cargo build --profile perry-dev -p perry -p perry-runtime-static -p perry-stdlib-static: clean; confirmed .a mtimes moved.
• cargo check --workspace --all-targets (default dev profile) under
  -D warnings: clean, excluding the cross-host UI crates per convention.
• cargo test -p perry-api-manifest: 39+4 passing.
• cargo test -p perry-codegen --test manifest_consistency: 5/5 passing.
• cargo test -p perry-hir --test unimplemented_api_check: 16/16 passing.
• cargo test -p perry --bin perry -- well_known binding_faithfulness optimized_libs: 70/70 passing (incl. the three edited tests above).
• python3 scripts/binding_governance.py --check: OK (39 extension crates).
• node scripts/binding_pins.mjs --check: OK (37 pinned, lock-step holds).
• python3 scripts/workspace_architecture.py --check: OK.
• cargo fmt --all -- --check: clean (fixed two trailing-blank-line diffs
  from block deletions).
• scripts/run_lint_gates.sh (SKIP_COMPILE_GATES=1): 76 of 77 passed
  (compile tier skipped). The one red, "Public benchmark evidence
  freshness", is pre-existing on every PR in this repo — not touched here.
• Real dotenv parse/config round-trip: see above, byte-for-byte
  identical to Node.

Not run / out of scope

• Compile tier of run_lint_gates.sh (known-red on Linux per this
  campaign's contract).
• Full gap suite (host stalls under auto-optimize per contract); ran the
  targeted registry/consistency tests plus the direct acceptance test
  instead.
• No version bump / CLAUDE.md edit — per this campaign's convention, the
  maintainer bumps at merge time.

Rebased onto main @ 053b9ccac4 (train 225, v0.5.1604)

Recomputed triple: workspace_members = 78, externalize = 29, keep = 44 (merge=1,
remove=1, review=3 unchanged; sum 78). Independently reproduced by
workspace_architecture.py --check --print-summary from the resolved tree, not taken
by arithmetic. Main's baseline at the time of this rebase is 79/30/44 — it already
carries #10701's uuid removal from train 225 — not the earlier 80/31/44. dotenv's own
decision is externalize, so 79→78 / 30→29 / 44 unchanged.

This rebase hit the same false-merge trap documented in #10739 and #10679:
workspace-architecture.json's baseline numbers and the deleted perry-ext-dotenv
crate entry sit on separate lines, so git's 3-way merge auto-resolved the numbers to
79/30/44 with zero conflict markers — silently wrong, since this branch's own
prior resolution and train 225's uuid removal had each independently rewritten that
line to the same value, and the merge needed to compose two decrements rather than
treat them as identical. Caught by recomputing from the tree instead of trusting the
clean auto-merge; corrected to 78/29/44 by hand before continuing, then confirmed by
the script.

Also re-derived rather than assumed: unrooted_local_shape_baseline.json (578,
unchanged — zero diff vs main) and native_result_ledger (green on main post-#10738:
376 rows / 326 providers; EXPECTED_ROWS untouched since there are no dotenv rows in
the tsv on either side). Cargo.toml version takes main's (0.5.1604); Cargo.lock
regenerated via cargo metadata --offline, not hand-merged. None of the at-cap files
from #10750 (perry-codegen/src/stmt/let_stmt.rs, perry-hir/src/lower/stmt_loops.rs,
perry-runtime/src/gc/tests/copying.rs, perry-runtime/…/module_keys.rs, and others)
are touched by this diff.

One additional conflict this rebase surfaced that the original resolution didn't need:
crates/perry/src/commands/compile/well_known.rs's shipped_unproven_bindings_are_partial
test array. Main's copy already dropped "uuid" (train 225); this branch's own commit
dropped "dotenv" from an older array that still had "uuid" in it. Resolved to
["nanoid"] — the only entry both changes agree should remain.

Gates re-run on the rebased tree: cargo fmt --check clean, cargo check --workspace --all-targets -D warnings clean (default dev profile — perry-ext-axios
is still present in the workspace on this branch since #10679 hasn't landed on main
yet, which is expected and correct for an independent removal), run_lint_gates.sh SKIP_COMPILE_GATES=1 78/79 (only the known pre-existing public-baseline red),
check_file_size.sh OK, git diff --stat empty after every gate run. No re-run of the
acceptance test — nothing in train 225 changes what dotenv/dotenv/config do, and it
was already validated and attributed (see the #10735 discussion in the dotenv/config
section above).

#10679 (axios) computed the same way and landed in train 226 at 78/29/44, which is why
main moved from 79/30/44 to 78/29/44 between this rebase and the previous one.

Re-derived again onto main @ 91a566c8af (train 226, v0.5.1605)

Train 226 took #10679, moving main from 79/30/44 to 78/29/44. This branch's
previous rebase computed its own removal against that same 79/30/44 main and landed on
78/29/44, which the moment #10679 merged became stale — it's now main's current
value, not this branch's post-removal value. Recomputed triple: workspace_members =
77, externalize = 28, keep = 44 (merge=1, remove=1, review=3 unchanged; sum 77),
independently reproduced by workspace_architecture.py --check --print-summary from
the resolved tree, not taken by arithmetic from main's 78/29/44.

Hit the exact same false-merge variant a third time on this same file: baseline numbers
auto-merged to 78/29/44 (main's pre-removal value) with zero conflict markers while the
crate map already had perry-ext-dotenv deleted (77 crates) — textually consistent
with "no conflict" but numerically stale. Corrected by hand, confirmed by the script.

Re-derived, not adjusted: unrooted_local_shape_baseline.json unchanged at 578 (zero
diff vs main), native_result_ledger green (376 rows / 326 providers, EXPECTED_ROWS
untouched — no dotenv rows in the tsv either side), Cargo.toml took main's version
(0.5.1605), Cargo.lock regenerated via cargo metadata --offline. All of #10750's
at-cap files confirmed untouched. All gates re-run clean: cargo fmt --check, cargo check --workspace --all-targets -D warnings (no perry-ext-axios present — confirms
it's gone from main; no perry-ext-dotenv — confirms this branch's own removal),
check_file_size.sh, run_lint_gates.sh SKIP_COMPILE_GATES=1 78/79 (only the known
public-baseline red), git diff --stat empty after each. No re-run of acceptance —
nothing in train 226 touches what dotenv/dotenv/config do.

The acceptance run here is strong on the library API but never exercises import "dotenv/config" — the side-effect auto-load subpath — and that is the one path this PR's own body identifies as newly at risk.

What is covered: real dotenv 17.2.3 with no compilePackages entry, an 18-key fixture with quoting / multiline / inline-# edge cases, parse() and config() byte-for-byte identical to Node 26.5.1. The quiet: true is legitimate — it suppresses dotenv's randomized tip banner, which is nondeterministic, and both sides ran with it.

What is not covered, and why it stands out:

The body notes that with the binding gone, resolve.rs's array no longer makes the module walker skip the node_modules/dotenv/ tree, so "dotenv's real source (including the dotenv/config auto-load subpath) needs to reach the walker like any other npm package." The PR then, reasonably, removes the coverage that subpath used to have:

• the dotenv/config half of lookup_preserves_registered_subpaths_before_falling_back
• the dotenv/config-only side-effect-only-module allowlists in unimplemented_api_check.rs and manifest_consistency.rs, trimmed to &[]

Each deletion is defensible on its own — the deleted tests' subject really was the now-removed native registration. The composition is what matters: the subpath loses its old coverage, gains none, and is the idiom the package is best known for (import 'dotenv/config' at the top of an entry file).

It is also the exact shape #10735 breaks — a side-effect module reached through require, where require.main === module is currently true in every compiled CommonJS module.

Suggested addition before this lands: one acceptance case doing import "dotenv/config" with DOTENV_CONFIG_PATH pointed at the fixture, reading process.env afterwards, diffed against Node 26.5.1.

If it fails because of #10735, that is not a reason to reject this PR — it is a reason to land #10735 first, and it would be a second independent confirmation that #10735 blocks real packages rather than merely looking bad. A removal does not cause the defects its acceptance run finds; it stops hiding them.

The general point, since it applies to every removal in this queue: a green acceptance run is evidence only about the paths it ran. Where a removal changes how a package is resolved, the acceptance should cover each entry point whose resolution changed, not only the primary one.

[proggeramlug]

Closing the gap I raised above. The dotenv/config subpath acceptance is sound for this PR's declared version, and it can be established from the packages rather than by re-running.

The concern was that the subpath fixture ran against dotenv 16.4.5, while this PR declares ^17.2.3. Testing a version the PR never installs is the trap that already bit us once today, so it needed answering rather than assuming.

Compared the two versions' entire resolution surface:

	result
exports map	identical (same keys, same targets — "./config": "./config.js", "./config.js": "./config.js", …)
main	identical — lib/main.js
config.js	byte-identical
lib/ file list	identical

config.js in both is the same IIFE:

(function () {
  require('./lib/main').config(
    Object.assign({}, require('./lib/env-options'), require('./lib/cli-options')(process.argv))
  )
})()

So the resolution path the fixture exercised — package exports → ./config → config.js → require('./lib/main') — is literally the same code and the same mapping in 17.2.3. The 16.4.5 result transfers on evidence, not on the assumption that neighbouring majors behave alike.

Worth stating what would have made this not transfer, since the distinction is the point: dotenv 18.0.1 restructured into a bundled dist/ (dist/index.cjs, dist/config.cjs) and introduced a require.main === module CLI guard that neither 16 nor 17 contains. A subpath result from 16.4.5 would have said nothing about 18. It says everything about 17.2.3 because the relevant files are the same bytes.

Combined with this PR's original acceptance — which did run on 17.2.3, covering parse() and config() byte-identically against Node 26.5.1 — both entry points whose resolution this removal changes are now covered on the declared version.

Ready for a train. Rebased onto 91a566c8af (v0.5.1605), MERGEABLE, headRefOid 3afb1f788d.

Recomputed triple: workspace_members=77 / externalize=28 / keep=44, against main's 78/29/44. Independently reproduced by workspace_architecture.py --check --print-summary rather than derived by arithmetic from main's values — stating it explicitly here because the recompute is the step that does not announce itself, and a green rebase implies nothing about it.

The stale-merge trap fired again, and this time the file disagreed with itself

workspace-architecture.json auto-merged with zero conflict markers to a stale 78/29/44 — while the crate map in that same file already had perry-ext-dotenv deleted, i.e. 77 crates. So the merge produced a file that was internally inconsistent and textually clean. Corrected by hand and confirmed by the script.

That is the third occurrence on this PR alone (79/30/44 → 78/29/44 → 77/28/44 as main moved beneath it), and the general mechanism is written up in #10739. The defence is unchanged: re-derive from the resolved tree every time; never compare the two sides, and never carry a value forward.

Everything else re-derived rather than adjusted

• scripts/unrooted_local_shape_baseline.json — unchanged at 578, verified by a zero diff against main rather than assumed.
• native_result_ledger — green at 376 rows / 326 providers, EXPECTED_ROWS untouched. Confirmed there are no dotenv rows on either side, so "no change" here is no change needed rather than change forgotten; those look identical in a diff.
• Cargo.toml took main's version; Cargo.lock regenerated via cargo metadata --offline, not hand-merged. It was the only real conflict.
• None of Fifteen files are within 10 lines of the 2,000-line cap and three have zero headroom — the next unrelated change to any of them owes a file split #10750's at-cap files are touched.

Gates: cargo fmt --all -- --check clean, cargo check --workspace --all-targets under -D warnings clean, run_lint_gates.sh 78/79 (only the known public-baseline red, diagnosed in #10707), check_file_size.sh OK, git diff --stat checked after every gate run.

No re-acceptance run: the parse()/config() acceptance on the declared ^17.2.3 and the dotenv/config subpath coverage both still stand, and nothing in trains 225 or 226 changes how dotenv resolves.

Note for whoever queues this: #10704 also computes to 77/28/44 against the current main. Whichever of the two lands second must re-derive — the counts are absolute, not deltas.

Landed in merge train 227 (#10763), released as v0.5.1606 — main is now 7fe8009492.

Closing rather than merging is how trains work here: both PRs were cherry-picked onto one tree, validated together, and landed under the train's own commit, so GitHub cannot mark this one merged even though your change is on main.

The workspace count triple was re-derived on the assembled tree rather than carried: 77 members / externalize=28 / keep=44. Ledger green at 376/326, unrooted_local_shape at 578.

Validation: all nine cheap gates, cargo check --workspace --all-targets under -D warnings, the release build of all five pinned artifacts, every unit suite, and a 7-area gap sweep (try, catch, error, throw, require, cjs, module) with zero unexplained regressions and each area asserted to have run a non-zero number of tests, at PERRY_RUN_TIMEOUT=30. lint completed its full 6-of-6 compile tier with nothing outside the known-red public-baseline step.
