feat(wire): snapshot delta encoding in push stream

Wall 16 root cause: C frames sent full 1071-entry snapshot manifests for every commit (50 commits × 128KB = ~4MB per frame), exceeding CF's gRPC per-message limit of ~248KB.

Fix: delta-encode snapshots in _frame_generator. - First snapshot in stream: full manifest - Each subsequent: delta(added, removed) against previous - Frame size now proportional to what changed (2-5 files ≈ 1KB per delta) - Server reconstructs full manifests via stream-local _snap_manifest_cache

New: compute_snapshot_delta, apply_snapshot_delta in muse.core.mpack New: write_commit_pack accepts snapshot_deltas=[...] Tests: test_snapshot_delta.py (10), test_wire_snapshot_delta.py (8)
