feat: reconnection, overlay UI, profile caching, history loading, log viewer, and about page

- Reconnection: unlimited retries with capped backoff, forceReconnect on foreground
  and manual refresh when offline
- Overlay: fix status bar coverage, remove scrim, fix IME layout (messages fixed
  at top, only full-screen IME pushes input), handle process-kill by eager
  ViewModel resolution with try-catch
- Profile: cache-first rendering, cloud refresh on each visit, silent fallback
  to cache on failure
- Messages: fix message swallowing by tracking DB observer job and using atomic
  StateFlow.update(), add dedicated isAssistantStreaming state for reliable
  typing indicator
- History: history_response handler now emits to live message stream, HTTP
  fallback waits for WS connection before requesting history
- Foreground: always request history on foreground to catch cross-device messages
- Log viewer: enhanced with All tab, auto-scroll, new categories (HTTP, voice, general),
  added log points for app lifecycle and overlay events
- Settings: added About page with project link (https://git.yeij.top/AskaEth/Cyrene-For-Android)
