Note

Medium Risk
Touches calendar sync invalidation on disconnect and sharing abort semantics; incorrect generation or flush scoping could cause stale reads or skipped writes, but changes are well covered by new tests.

Overview
Improves desktop responsiveness by not blocking the local DB write queue on slow network work, flushing only relevant write keys before reads, and letting users dismiss in-flight share preparation.

Database write queue adds flushDatabaseWritesByPrefix and flushDatabaseWritesWithin (5s timeout on exit/relaunch) so lifecycle and cache maintenance do not wait on unrelated pending writes.

Calendar sync serializes runs in an in-memory enqueueCalendarSync tail instead of holding the calendar-sync queue key for the whole fetch; persistence stays on calendar-sync for inventory and connection snapshots. Disconnect bumps a generation and filters stale connections so late discovery cannot restore removed accounts.

Session sharing tracks active preparation identity, aborts on popover close/account/note switch, and treats ShareOperationAbortedError as silent in mutation toasts; the loading popover can close via Escape/Done without blocking on pending work. Sync-state loads pass sessionId and flush only that session plus the viewer’s shared-note cache.

Shared-note / attachment cache paths flush targeted keys (e.g. session:{id}, shared-note-cache:{viewer}) instead of draining the full queue.

Disconnect aborts all calendar syncs

Medium Severity

removeDisconnectedCalendarConnection bumps calendarSyncGeneration, which makes isStopped true for every in-flight sync, including unrelated connections. The disconnect deeplink path only tombstones and does not schedule a follow-up sync, so remaining calendars can stay unsynced until some later unrelated trigger.
