Ping QiuandClaude Opus 4.6 d874e21f93 feat: Phase 5 CP5-2 -- CoW snapshots, 10 tests ...

Sparse delta-file snapshots with copy-on-write in the flusher.
Zero write-path overhead when no snapshot is active.

New: snapshot.go (SnapshotBitmap, SnapshotHeader, delta file I/O)
Modified: flusher.go (flushMu, CoW phase in FlushOnce, PauseAndFlush)
Modified: blockvol.go (Create/Read/Delete/Restore/ListSnapshots, recovery)
Modified: wal_writer.go (Reset for snapshot restore)
