useBookmarks / useReminders / useUserNotes were near-verbatim copies of a
concurrency-critical engine (module-scoped singleton, per-client
subscribe/teardown, a serialized write-queue that prevents lost-update
clobbering, a listener Set, and the account-data subscription).
Extract it into createAccountDataListStore<T, C>({ eventType, read, write }) in
src/app/hooks/createAccountDataListStore.ts. The write-serialization semantics
are preserved identically (still the lost-update fix). The differing payload
shapes are parameterized via read/write: bookmarks/reminders wrap a list
({bookmarks}/{reminders}); notes is a flat Record passed through unchanged.
The three hooks become thin wrappers with their exact public APIs unchanged
(same exported names, signatures, return shapes, and mutators), so no call site
changes. The DP16 setAccountData helper is used inside the queue.

Add centralized typed helpers in src/app/utils/accountData.ts:
- getAccountData<T>(mx, eventType): T | undefined (returns content)
- setAccountData<T>(mx, eventType, content): Promise<void>
These wrap the single `as any` cast needed because matrix-js-sdk's typed
overloads reject the fork's custom account-data event names. Every call site
now stays fully typed on its content shape.
Route all account-data reads/writes that previously used
`(mx as any).getAccountData/setAccountData` or `mx.getAccountData(... as any)`
through the helpers (or, where a MatrixEvent is needed, through the existing
utils/room.ts getAccountData whose param is widened to accept string keys).
No behavior change: same event types, same content shapes.

Web fixes from the Wave-2 bug-hunt (findings in LOTUS_TODO):
- F1 (security): wipe the decrypted-plaintext search index on SERVER-FORCED
logout too (token expiry / remote sign-out) — only manual logout did before.
F4: the delete no longer reports success while onblocked (waits, 3s cap).
- M1/M2 (data-loss): useBookmarks + useUserNotes account-data writes are now
serialized at MODULE scope (single queue + latestRef per client, echo-driven),
fixing the cross-instance lost-update clobber (useBookmarks mounts per message
row, so a per-instance queue was insufficient — caught in review).
- M6: room-history export gets a 200-page cap + Cancel + unmount-abort +
correct date-range early-break (raw paginated ts). M4: image compression
skips PNG (was flattening transparency to black), bakes EXIF orientation via
createImageBitmap, .jpg-renames, and falls back to the original on decode
failure instead of dropping the file. M5: MediaGallery lightbox opens the
right item (shared thumb guard). M8: audio speed survives async decrypt.
- Desktop web wiring: D2 badge sums leaf rooms only (space double-count, like
the favicon fix); D3 useTauriDnd re-hydrates from get_tray_dnd on mount; D5
updater has a terminal state.
Reviewed; M7 reverted (past-time clamp is an intentional, tested contract).
tsc/eslint/prettier clean, build OK, 678 tests.

P3-1: Message Bookmarks — right-click any message to bookmark; saved to
io.lotus.bookmarks account data (max 500, syncs across devices); star
icon in sidebar opens BookmarksPanel with filter, Jump-to-message, and
remove buttons; reactive to AccountData events
P3-2: Message Scheduling (MSC4140) — clock button next to send opens
ScheduleMessageModal with datetime-local picker; validates ≥1 min future;
calls PUT org.matrix.msc4140 delayed event API; collapsible
ScheduledMessagesTray above composer lists pending messages with cancel;
local Jotai atom tracks scheduled messages per room
P3-3: File Upload Compression — opt-in checkbox per JPEG/PNG file ≥200KB
in upload preview; canvas API compresses at 0.82 quality; shows before/
after size estimate; compressed blob used in upload when checked
P3-7: Room Insights — new Insights tab in room settings; top 5 active
members (bar chart), top 5 reactions (chips), media breakdown (4 tiles),
24-hour activity heatmap (CSS bar chart); all from local cache only with
disclaimer banner; never the first tab shown
