Implement block-level checksum: Phase 1-4 complete
Phase 1: VfsBlockChecksum struct + JSON storage (~240 lines)
- VfsBlockChecksum: offset + SHA-256 hash
- VfsChecksumFile: block_size + algorithm + blocks + file_size
- compute_block_hash() + verify_block_hash()
- ChecksumMode: Lazy (default) + OnRead
- ScrubResult: total/verified/corrupted/repaired blocks metrics
Phase 2: ChecksumFile wrapper (~180 lines)
- VfsFile wrapper with transparent checksum
- Lazy verification (only on scrub)
- Cache of verified blocks
- Update checksum on flush()
- read_at/write_at support
Phase 3: Scrub API (~150 lines)
- scrub_file(): verify single file integrity
- scrub_all(): recursive directory scrub
- create_checksums_for_file(): generate checksums
- repair_block(): placeholder for RAID/Dedup
Phase 4: RAID repair integration (~160 lines)
- repair_block_from_parity(): reconstruct from RAID parity
- reconstruct_from_p(): XOR reconstruction for RaidZ1
- reconstruct_from_pq/pqr(): placeholder for RaidZ2/3
Tests: 15 checksum tests pass (465 total)
