docs: release merged Codex claim files

[AceHack]

What changed

• Adds a Codex release claim for merged-claim cleanup.
• Removes stale Codex claim files for merged PRs hygiene: validate bash retirement allowlist integrity #5358 and hygiene: format stale worktree auditor #5360.

Why

Those claim files remained on main after their owning PRs merged, so they no longer represent active work and should not be counted as current Codex ownership.

Checks

• git status --short --branch
• git diff --cached --check before commit
• scoped file existence/removal check
• bun .codex/bin/codex-loop-health.ts
