Ping QiuandClaude Opus 4.6 3ddb87adc9 fix: superblock write coordination (superMu) + remove debug logs
Adds sync.Mutex (superMu) to BlockVol, shared between group commit's
syncWithWALProgress() and flusher's updateSuperblockCheckpoint().
Both paths now serialize superblock mutation + persist, preventing
WALTail/WALCheckpointLSN regression when flusher and group commit
write the full superblock concurrently.

persistSuperblock() also guarded for consistency.

Removes temporary log.Printf lines in the open/recovery path that
were added during BUG-RESTART-ZEROS investigation.
