feat(claude-code): update placemat for Claude Code v2.1.295

[dommango]

What this changes

Syncs the Claude Code placemat from v2.1.293 to v2.1.295 (npm dist-tags.latest, cross-checked against the official changelog). v2.1.294 was bug-fix-only (more accurate judging of prompt/agent-type hooks written as plain-English instructions) and gets no changelog entry, matching the existing treatment of other placemat-irrelevant releases like v2.1.291.

v2.1.295 additions:

• onFailure: "block" hook field for command/HTTP hooks — new row in the Event Hooks group
• CLAUDE_CODE_RETRY_WATCHDOG_MAX_WAIT_MS env var — new row next to CLAUDE_CODE_RETRY_WATCHDOG
• forceLoginGatewayUrl/forceLoginMethod: "gateway" now also work as a user setting on machines with no managed settings — summary rewritten (no longer "Managed setting"-only) and a note added
• /copy picker's quoted-text handling (copies without leading > markers) — converted to a two-tier cell with a note
• claude plugin validate's new README install-line advice — note added to the existing row

Header release tag, print-head, and footer sync date all updated to v2.1.295 / 2026-10-08. sources.json's inventory.hooks gained onFailure, inventory.fetched bumped to 2026-10-09, and five new gotchas record what's changelog-only vs. reference-confirmed.

Type

• Content correction (wrong/outdated/missing entry)

Checklist

• I read AGENTS.md's Style Guide and Content Rules
• node tests/placemat.test.js passes locally (54/54 for claude-code, 218/218 overall)
• node scripts/build-changes.js --all --check passes locally (generated files are fresh)
• No versions/*.html files were edited
• No hand-edited changes.json or feed.xml — both regenerated via the generator
• Every new/changed row is sourced from code.claude.com/docs (hooks.md, env-vars.md, commands.md, plugins/cli-reference.md) or the official changelog — never copied or inferred from a sibling placemat
• Nothing here required class="unverified" — all new items are confirmed either directly in a reference page or verbatim in the official changelog (release_notes rule)
• New rows have an id="i-<slug>" and a matching .row-link permalink
• Only claude-code/ is touched

Merge-gate review (code-review skill, medium effort)

Reviewed origin/main...HEAD (1 commit, 5 files, all under claude-code/).

Checks run:

• node scripts/build-changes.js claude-code --check → generated files (changes.json, feed.xml) match changelog.html, no staleness
• node tests/placemat.test.js claude-code → 54/54 passed
• feed.xml validated as well-formed Atom XML
• Confirmed no cross-agent contamination (only claude-code/* touched)
• Verified new row ids against the AGENTS.md slug-derivation rule (onFailure: "block" → i-onfailure-block, CLAUDE_CODE_RETRY_WATCHDOG_MAX_WAIT_MS → i-claude-code-retry-watchdog-max-wait-ms) — both correct
• Checked the forceLoginGatewayUrl summary rewrite against the "rewrite instead of extend" house rule — correctly applied, since the setting is no longer managed-only
• Checked onFailure's placement in sources.json's inventory.hooks array — correctly alphabetical
• Found 11 pre-existing class="new"/<!-- added:vX.Y.Z --> occurrences and some pre-existing >90-char summaries in index.html — confirmed both predate this PR (same count on main) and are untouched by this diff, so out of scope rather than something this PR introduces

Verdict: no CRITICAL/HIGH findings. Clean — proceeding to merge per the pipeline's Step 10.
