refactor(stdlib): remove validator native binding

[proggeramlug]

Summary

Removes the native validator binding so import validator from "validator"
(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

Native validator has 9+ methods that throw "not implemented"
(trim/contains/equals/isAlpha/isNumeric/isLength/escape/
isMobilePhone/isCreditCard/isISBN/normalizeEmail, etc.). trim()
specifically doesn't throw — it silently returns undefined. The five
methods that are implemented (isEmail/isURL/isUUID/isJSON/
isEmpty) return 0/1 rather than real JS booleans, visible via
JSON.stringify(validator.isEmail(x)) printing "1" instead of "true" (a
typeof check or strict === true comparison silently fails). Real npm
validator matches Node for all 50 checks.

What was found and removed

Per #10678 (duplicate extern "C" exports across perry-ext-*/perry-stdlib
pairs), this binding existed twice, plus a shared helper crate used only
by the two duplicates:

• crates/perry-ext-validator/ — the governance-tracked binding crate,
  wired into well_known_bindings.toml's [bindings.validator].
• crates/perry-stdlib/src/validator.rs (425 lines) — a second, independent
  implementation behind the bundled-validator feature (default-on via the
  validation umbrella, itself in the full feature), exporting the same
  16 js_validator_* symbols.
• crates/perry-validation/ — its own doc comment: "Fixed-grammar
  validators shared by Perry's two validator bindings". A small email/URL/
  UUID grammar helper crate consumed exclusively by the two crates above
  (confirmed via grep: no other crate depends on it). With both bindings
  gone, nothing references it, so it goes too.

All three removed, plus every registry row:

• The 5-entry NativeModSig dispatch block in native_table/utils_crypto.rs
  (isEmail/isURL/isUUID/isJSON/isEmpty — the only validator methods
  with a dedicated codegen row; every other check was reachable only through
  the deleted FFI crates, which is exactly the "9+ methods throw not
  implemented" bug).
• The 16 js_validator_* FFI declarations in
  runtime_decls/stdlib_ffi/streams_events.rs.
• [bindings.validator] + .upstream in well_known_bindings.toml.
• The "validator" NATIVE_MODULES entry and its 5 manifest rows in
  perry-api-manifest.
• The validation/bundled-validator stdlib features (and "validation"
  from perry-stdlib's own full feature list).
• 16 Android stub exports in perry-ui-android/src/stdlib_stubs.rs.
• The perry-ext-validator and perry-validation workspace members + path
  dependencies in the root Cargo.toml.
• workspace-architecture.json's two crate decision entries
  (workspace_members 83→81, externalize 33→32, keep 45→44 — two crates
  removed: perry-ext-validator was externalize, perry-validation was
  keep/runtime-core).
• 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 with an explicit feature list that
  included "validation" — 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/, per this campaign's own guidance that the binding gates don't
  catch these.

Left alone

Prose comments/usages in crates/perry/tests/issue_6559_dyn_function_interpreter.rs
(new Function("validator", "serializer", code) — "validator" is a
parameter name in a dyn_eval test, unrelated), and any generic
type-validation infrastructure (param_guard.rs, validators.rs,
net_validate.rs, etc. — these implement Perry's own runtime type/argument
checking, an unrelated meaning of "validate").

Acceptance test: several validators, no compilePackages entry

{ "dependencies": { "validator": "^13.15.0" } }

Covers the 5 checks the wrapper had, plus several it threw "not implemented"
for (trim, isAlpha, isNumeric, contains, equals, isLength,
escape, isMobilePhone, isCreditCard, isISBN, isHexadecimal,
isLowercase, isUppercase, isInt, isFloat, normalizeEmail).

Built on perrymaster (--profile perry-dev), compile log: 114 native modules
from the real validator package (no compilePackages entry). Ran the
binary and diffed against node --experimental-strip-types (Node 26.5.1):
byte-for-byte identical — every value now prints as a real JSON boolean
(true/false), not 1/0, and every previously-throwing method now
returns the correct value.

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.
• 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 one trailing-blank-line diff
  from the block deletion in streams_events.rs).
• 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 validator 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.

Summary by CodeRabbit

• Breaking Changes
  • Removed the bundled validator native binding and built-in API declarations.
  • Direct imports of the previously bundled validator methods may now produce R005 UnimplementedApi.
  • Removed the associated validation feature and standalone validator packages.
• Documentation
  • Updated API references and governance documentation to reflect removal of the validator module.

Update the remaining validator documentation.

docs/native-libraries.md, Lines 692-741 still identifies validator as Rust-backed and documents the removed native API. This contradicts the new npm-package resolution. Remove that section or update it to describe the real npm package.

Landed in merge train 222 (#10732), released as v0.5.1601 — main is now 7c5d04d0ea.

Closing rather than merging is how trains work here: the eight 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. git log origin/main will show your commits.

Close-keywords in a source PR body never fire under this scheme, so the issues this train resolved were closed from the train's body instead.

The tree passed: all nine cheap gates, cargo check --workspace --all-targets under -D warnings, the release build of all five pinned artifacts, every unit suite, both derived integration suites, and a 14-area gap sweep with zero unexplained regressions and every area asserted to have run a non-zero number of tests. lint completed its full 6-of-6 compile tier with no failure outside the known-red public-baseline step.
