refactor: improve agent notification types and fix activity curator
- Convert agent notifications to discriminated union (session/permission/status)
- Fix activity curator to properly handle typed session updates
- Serialize Date objects in AgentInfo for JSON compatibility
- Use activity curator for title generation context
- Reduce console.error to console.warn for non-critical WebSocket errors
- Improve spacing in agent stream views
- Delay title generation until 15+ updates available
```
feat: implement agent permission flow with gesture-based sidebar navigation
Add permission request/response system for agent tool calls with UI approval flow, implement swipeable agent sidebar with edge gesture detection, and enhance agent updates with stable message IDs for proper deduplication across reconnections.

refactor: convert AgentManager to global singleton across sessions
Move AgentManager initialization from per-session to single global instance. Agents now persist across sessions, with sessions subscribing/unsubscribing to agent updates rather than creating/destroying agents.
```
**Agent Activity UI Improvements:**
- Create typed discriminated unions for SessionNotification updates
- Add AgentActivity component with specialized rendering for each update type
- Group consecutive text chunks into single messages (like main chat)
- Add collapsible tool call rendering with input/output details
- Add plan rendering with task status indicators
- Add fallback rendering for unknown activity types (badge + drawer)
**Agent Status Update Fix:**
- Fix agent killing not updating UI status
- Session now detects status change notifications and emits agent_status messages
- Agent manager delays agent deletion to allow status updates to propagate
- Frontend agent_status handler now receives proper updates
**Technical Details:**
- Created /packages/app/src/types/agent-activity.ts with typed session updates
- Created /packages/app/src/components/agent-activity.tsx with activity renderers
- Updated AgentStreamView to use grouped activities with useMemo
- Modified session.ts subscribeToAgent to emit agent_status on status changes
- Modified agent-manager.ts killAgent to delay deletion for status propagation
