The RecordSyncFailure and ResetBackoffOnDaemonStart functions had a
TOCTOU (time-of-check-time-of-use) race condition. They called
LoadSyncState (which locks, reads, unlocks) then modified the state,
then called SaveSyncState (which locks, writes, unlocks).
Between LoadSyncState returning and SaveSyncState being called, another
goroutine could load the old state, modify it, and save it - then this
goroutine's save would overwrite those changes.
Fix: Create internal unlocked helper functions (loadSyncStateUnlocked,
saveSyncStateUnlocked) and have RecordSyncFailure and
ResetBackoffOnDaemonStart hold the lock for the entire load-modify-save
operation.

Analysis found these commands are dead code:
- gt never calls `bd pin` - uses `bd update --status=pinned` instead
- Beads.Pin() wrapper exists but is never called
- bd hook functionality duplicated by gt mol status
- Code comment says "pinned field is cosmetic for bd hook visibility"
Removed:
- cmd/bd/pin.go
- cmd/bd/unpin.go
- cmd/bd/hook.go
