Key Highlights

Fix observation persistence on fresh installs (#2139)
Added addPendingMessagesToolUseIdAndWorkerPidColumns mirror in SessionStore.ts
Self-healing for already-broken DBs at v29 with no v28 columns
Transaction-wrapped dedup DELETE + UNIQUE index creation

Full Release Notes

## Bug Fixes

- **Fix observation persistence on fresh installs (#2139)**: `SessionStore` was missing migration 28's column additions, so freshly created `pending_messages` tables had no `tool_use_id` or `worker_pid` columns. Every queue claim and observation insert failed silently with "no such column" errors and nothing reached memory. Added `addPendingMessagesToolUseIdAndWorkerPidColumns` mirror in `SessionStore.ts` (matches the existing `addObservationSubagentColumns` / `addObservationsUniqueContentHashIndex` mirror pattern). Already-broken DBs at "v29 with no v28 columns" self-heal on next worker boot via column-existence guards. Dedup DELETE + UNIQUE index creation are now wrapped in a transaction matching the v29 mirror precedent.
