Warren f016525687 Implement VFS snapshot support (ZFS-style) ...

- Add VfsSnapshotInfo struct
- Add snapshot methods to VfsBackend trait:
  - create_snapshot: copy-on-write with metadata
  - list_snapshots: enumerate snapshots
  - delete_snapshot: remove snapshot and metadata
  - restore_snapshot: restore from snapshot
  - snapshot_info: get snapshot metadata
- Implement LocalFs snapshot support:
  - Uses .snapshots directory for storage
  - JSON metadata files (*.meta)
  - Recursive directory copy
  - Size calculation

This enables SMB 'Previous versions' feature foundation.

All 229 tests pass.
