feat: Phase 1 complete — Matrix login, rooms, chat, profile
- Direct m.login.password auth against matrix.m8chat.au - Room list with unread badges, last message, timestamps - Chat timeline (text, images, files, replies, reactions) - Profile screen with expandable Notifications and Security sections - Olm E2EE initialisation (web WASM bootstrap) - Global error handler preventing Matrix SDK crashes - GoRouter with refreshListenable (no recreation on auth change) - Feature-first clean architecture: Riverpod + GoRouter + Drift - Deployed to https://app2.m8chat.au Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
