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
```
Instead of showing tool_call and tool_call_update as separate events,
now merge them by toolCallId into a single MergedToolCall that updates
as new information comes in.
**Changes:**
- Added MergedToolCall type with start/end timestamps
- Renamed groupTextChunks to groupActivities with tool call merging logic
- Track tool calls by ID and merge all updates into single entry
- Replace ToolCallItem with MergedToolCallItem component
- AgentStreamView now uses groupActivities for unified grouping
**User Experience:**
- Each tool call appears once and updates in place
- Status changes from pending → in_progress → completed
- Input/output merge as they become available
- Cleaner, less noisy activity view

**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
