feat: add visual todo list panel

- Add TodoPanel component to display TodoWrite tool calls
- Create todos Svelte store to track todo state
- Emit todo-update Tauri event when TodoWrite is called
- Add todo button to status bar (next to session history)
- Display todos with status icons, progress bar, and completion count
- Real-time updates as I work through tasks

Closes #132
