chore(#2896): convert CONTEXT.md prose defect registry into enforced gates (#3325)

* chore(#2896): convert CONTEXT.md prose defect registry into enforced gates

Squashes the prior 4-commit sequence and fixes defects found while
resuming this branch: 5 orphaned/corrupted DEFECT fragment lines left
by an earlier botched edit, 17 "Source of truth: Memtrace `find_symbol`"
placeholders that had destroyed real file-path citations, and 3
DEFECT.GENERATIVE-* entries merged into one RULESET.GENERATIVE-FIX
predicate (policy, not an unenforced defect) to satisfy the zero
DEFECT.<NAME>.<field>= acceptance criterion.

Six mechanizable defects get real gates: DEFECT.UNBOUNDED-SUBPROCESS
(eslint-rules/require-subprocess-timeout.cjs), DEFECT.CANARY-VERSION-LEAK
(scripts/lint-canary-version-leak.cjs + version-gate.yml),
DEFECT.CHANGESET-PR-FIELD-DRIFT (findPrFieldDrift in changeset/lint.cjs),
DEFECT.FRONTMATTER-SCALAR-BROAD-GREP, DEFECT.REMOVED-BUT-NEEDED, and
DEFECT.DEFAULT-FLIP-DOCUMENTATION (new lint scripts, wired into lint:ci).
Already-enforced and unenforceable prose entries are deleted; the gate
is the record.

* chore(#2896): route the new lint tests' subprocess calls through the bounded process-seam helper

The 4 new test files for this PR's lint checks called cp.spawnSync/
execFileSync directly with no timeout, tripping this repo's own
existing local/no-unbounded-spawn ESLint rule. Route every one through
runNode/gitOrThrow (tests/helpers/process-seam.cjs,
tests/helpers/git-fixture.cjs) instead, matching the pattern already
used elsewhere in the suite (e.g. tests/changeset-lint.test.cjs).

* fix: register claude-orchestration.cjs and regenerate stale generated indexes

Pre-existing drift on next, unrelated to this PR's own change, surfaced
by running lint:ci as part of verifying #2896: two cli_modules
(claude-orchestration.cjs, write-set.cjs) landed without a manifest
regen, and CONTEXT.md's own edits in this PR staled its two generated
indexes. Adds the missing docs/INVENTORY.md row for
claude-orchestration.cjs (write-set.cjs already had one — only its
manifest entry was stale) and regenerates
docs/INVENTORY-MANIFEST.json, docs/CONTEXT-INDEX.json, and
examples/dynamic-context-management/CONTEXT-INDEX.json.

* fix(#2896): default-flip-documentation lint's local fallback base was main, not next

Found in review: every other base-ref fallback in this repo (see
scripts/changeset/lint.cjs's DEFAULT_BASE, #2988) defaults to `next`,
the integration branch every PR actually targets — `main` is the
release branch. This script's local fallback (used only when
GITHUB_BASE_REF is unset, i.e. never in CI, but potentially on a local
or direct invocation) diffed against the wrong ref. No test exercised
the unset-env-var path, so it shipped unnoticed; every e2e test sets
GITHUB_BASE_REF explicitly and is unaffected by this fix.

* fix(#2896): stale eslint comment, overclaiming CONTEXT.md wording, and an incompletely-regenerated manifest

Found by the isolated Standards code-review pass:
- eslint.config.mjs's require-subprocess-timeout comment said "'warn'
  for now... flip to 'error' once migrated" while the rule already
  shipped as 'error' with all 8 sites migrated in the same commit —
  described a state that never existed.
- The CONTEXT.md pointer block claimed the rule's bounded call sites
  "never throw", but roadmap-upgrade.cts's pre-mutation clean-tree
  check correctly still throws on failure (it gates a destructive
  real-run migration; degrading to "assume clean" would risk clobbering
  uncommitted work) — softened the claim to describe both shapes
  accurately instead of overclaiming one.
- docs/INVENTORY-MANIFEST.json's claude-orchestration.cjs/write-set.cjs
  entries from the prior "fix: register claude-orchestration.cjs..."
  commit didn't actually land — re-running the generator now includes
  them; lint:generated-sync is green.

* chore(#2896): backfill changeset pr field with the real PR number

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

* fix(#2896): normalize buildCorpus file paths to POSIX in lint-removed-but-needed

Windows CI caught it: path.relative(root, abs) returns backslash-
separated paths on Windows, but findSurvivingReferences's package-lock
special case does file.startsWith('.github/workflows') — a forward-
slash literal. On Windows the check silently never matched, so
tests/removed-but-needed-lint.test.cjs's real-defect-shape fixture got
exit 0 instead of the expected exit 1. Normalize at the production
source (RULESET.CONTENT-PATH-NORMALIZATION) rather than the test side.

* the real PR number after `gh api POST /pulls` returned it.
*
* Pure: given `prEntries` (`[{ file, pr }]`, one entry per successfully
* parsed changed fragment — `pr` is always a positive integer, since
* `parseFragment` already rejects `pr: 0` / non-numeric values as
* `invalid_pr` before a fragment ever reaches this function) and
* `realPrNumber` (the PR this run belongs to, or `null` when unknown —
* push/non-PR runs), returns every fragment whose `pr` disagrees with
* `realPrNumber`. `realPrNumber == null` always yields `[]`: with no PR
* event payload to compare against, there is nothing to drift-check.
*
* `pr === 0` is always silent regardless of `realPrNumber` — CONTRIBUTING.md
* documents `pr: 0` as the deliberate placeholder used "during initial
* commit" before `gh api POST /pulls` returns the real number, so it is not
* yet a drifted value, just an unbackfilled one. (In practice `parseFragment`
* already rejects `pr: 0` as `invalid_pr` before a fragment reaches this
* function via `main()`'s wiring — this guard documents and locks in the
* pure function's own contract independent of that upstream check.)
