refactor(docs): relocate verbose release process to docs/RELEASING.md

The highest-/ship-risk commit (isolated so it can revert alone). Moves the verbose
release + contributor procedure out of CLAUDE.md, keeping every ship-critical IRON
RULE inline so /ship + /document-release (which read CLAUDE.md) cannot regress.

Moved to docs/RELEASING.md: pre-ship test requirements; the CHANGELOG-branch-scoped
+ CHANGELOG voice + release-summary template; the 'To take advantage of vX' block
spec; version migrations + migration-is-canonical; schema state tracking; GitHub
Actions SHA maintenance; PR-descriptions-cover-the-branch; community-PR-wave;
checking-out-PRs-from-garrytan-agents.

Kept INLINE in CLAUDE.md (ship-critical IRON RULES — do NOT move):
- the Version-locations table (5-file sync) + the 3-line consistency audit
- Conductor branch=workspace
- Post-ship /document-release (MANDATORY)
- Privacy + Responsible-disclosure rules (Privacy also anchors the check-privacy
  allowlist — the only place allowed to name the fork)
- PR-title-version-first
- never-hand-roll-ship (Skill routing)
Plus a new ## Releasing pointer ('Before any ship, read docs/RELEASING.md in full')
and a resolver row.

CLAUDE.md 61KB -> 39KB (592KB -> 39KB overall, 93% cut; ~9k tokens auto-loaded vs
~147k). CLAUDE.md size-gate tightened 90KB -> 60KB. The content-contract tests pin
that the inline IRON RULES (MAJOR.MINOR.PATCH.MICRO, document-release, hand-roll
ship) did NOT move out. The moved ranges carry no banned fork name, so RELEASING.md
needs no privacy allowlist entry. verify 30/30; bundle 225KB -> 204KB.
