feat: reimagine format-patch + apply-patch as content-addressed, domain-aware, Cohen-labeled Muse patch objects

Replaces the git-style unified diff export with a fully reimagined patch system built for the agent-first era:

- patch_id = sha256(canonical JSON) — any tampering detected before disk write - Cohen action labels on every op: inserted/deleted/modified/moved/renamed - Self-contained .mpatch files embed blobs (base64) for portable transport - applicability block: requires_snapshot, independent_dimensions, conflict_free - elapsed_seconds + exit_code in all JSON output paths - apply-patch: --dry-run, --check, --force; seeds object store from blobs - Full test coverage: unit, integration, data-integrity, security, performance
