Adds `packages/mobile` — an Expo SDK 53 React Native app for monitoring
agent sessions from a phone.
Features:
- Home screen: Kanban-style session list sorted by attention level
- Session detail: metadata, PR link, CI status, branch info
- Terminal screen: full xterm.js terminal via WebView (port 14801)
- Settings screen: configurable backend URL (LAN IP or ngrok)
- Push notifications: background polling for attention-level changes
Improvements over PR #235:
- Fixed terminal onmessage handler to filter JSON control messages
(resize echoes no longer render as garbage text)
- Removed duplicate terminal.html (single source of truth in
terminal-html.ts)
- Fixed isDone check to include "cleanup" status using isTerminal()
Tech: Expo SDK 53, React Navigation 6, React Native WebView.
Two server connections: REST API (port 3000) + WebSocket terminal (14801).
The mobile package is excluded from the pnpm workspace to avoid
interfering with the monorepo toolchain.
Closes#265
