byGalax de431386ea feat: reply + search + forward + archive/mute + error boundary
Messages:
- Reply-to: hover action, composer chip with cancel, quote bubble inside
  the replying message with tap-to-jump + amber highlight ring
- Search: header search button toggles in-conversation search bar with
  prev/next + match counter, auto-jump to active match
- Forward: multi-select conversation picker. Attachments are now carried
  over: download + decrypt source, re-encrypt under each target conv-key,
  re-upload with fresh per-attachment keys, insert new attachment rows

Conversations:
- Archive + mute per member. New migration 20260420000001 adds `archived`
  + `muted_until` on conversation_members. Shared helpers:
  setConversationArchived / setConversationMutedUntil / isConversationMuted
- ChatsPage: archive toggle in header with unread badge for archived
  bucket, split active/archived lists, muted indicator (BellOff icon,
  dimmed unread badge)
- ConversationRowMenu via createPortal (escapes sidebar overflow clip),
  forwardRef-based MenuItem so submenu positioning refs survive React 18
- ConversationsContext: suppresses notification sound + OS notif when
  target conversation is muted
- Refresh on `profiles UPDATE` realtime so peer avatar / displayName
  changes flow to conversation.members without manual refresh

Resilience:
- ErrorBoundary (Discord-style): centred spinner + escalating copy, no
  manual reload button. Backoff retry schedule [2s, 4s, 8s, 15s, 30s].
  Uses a keyed Fragment (not a div wrapper) so flex h-full chains survive
- App wrapped root + per-route RouteBoundary, conversation-level boundary
- AuthContext: flip `ready` immediately on cached session read; validate
  getUser in background so a stalled/offline Supabase doesn't freeze the
  app on the loading spinner

Crypto:
- Swap libsodium-wrappers -> libsodium-wrappers-sumo (compact build was
  missing crypto_pwhash so Argon2id vault KDF threw, falling back to
  plaintext localStorage on every launch)
- Shim d.ts for sumo types (sumo is API superset, no official types ship)
- vite optimizeDeps includes sumo with the "require" condition
- secureFileStore: exists(dir) check before mkdir; surface genuine
  permission errors instead of silent catch

Tauri:
- fs scope adds `$APPLOCALDATA` direct entry (not just /**) so the app
  data directory itself can be mkdir'd on first launch

Chat layout:
- Skip call_event messages when computing avatar run boundaries so a
  regular bubble followed by a call event from the same sender still
  shows its avatar
