feat: implement muse patch-id — content-based commit identity

- _compute_patch_id: SHA-256 of sorted-file unified diff content lines (+/- only, no @@ or file headers); --stable strips trailing whitespace so cosmetic differences don't produce new patch-ids - _resolve_commit: resolves HEAD, branch names, and commit IDs to CommitRecord - run: resolves commit → loads parent manifest → computes patch-id → text output '<patch_id> <commit_id>' or JSON with subject line - ANSI/control-char rejection in ref argument - 16 tests: unit (same diff = same id, different = different, whitespace normalization, deterministic empty diff), integration (JSON schema, text format, specific commit, branch ref, error cases), security (ANSI rejected), stress (10 distinct diffs produce 10 distinct patch-ids)
