weiihann 859312d1f5 nomt/bitbox: add Phase 4 WAL, sync controller, and crash recovery 
Implement crash-safe persistence for the Bitbox hash table:
- wal.go: WAL format with START/CLEAR/UPDATE/END entries, builder/reader
- sync.go: 3-phase sync protocol (BeginSync → WriteWAL → CommitSync)
- recover.go: WAL replay for crash recovery

The WAL records page diffs (not full pages) for compact logging. The
3-phase protocol ensures: WAL fsynced before HT modification, HT fsynced
before WAL truncation, providing at-least-once delivery of page updates.
