v0.2.47

Performance Improvements

Parallel Blob Sync

• Load 4 blobs from disk simultaneously during sync
• Faster image/attachment syncing

Connection Health

• Ping interval: 30s → 15s (detect stale connections faster)
• Reconnect backoff: 1s → 500ms (reconnect quicker)
• Sync check interval: 60s → 30s (more frequent sync attempts)

These changes improve responsiveness when connections drop and recover.
