docs/**/*.md is deny-listed from the CI cache hash (test-irrelevant). The
CLAUDE.md restructure moves test/release POLICY into docs/TESTING.md +
docs/RELEASING.md, which DO carry contracts the test suite reads. Without
re-admitting them, a policy-only edit would produce the same cache hash and
skip the test shard that runs the build-llms + doc-history guards (false-pass).
Adds an ALLOW_PATTERNS re-admit step after the deny, scoped to the named
policy docs (not a blanket docs un-deny). Lands FIRST, before any doc moves.
Pinned by 3 new cases in test/scripts/ci-cache-hash.test.ts: TESTING.md +
RELEASING.md edits MUST change the hash; docs/guide.md still must not.
