feat: move task details to top activity bar (#5652)

- Created new TaskActivityBar component to display task details at the top
- Simplified TaskHeader to only show context window progress and todo list
- Updated ChatView to integrate both components properly
- Maintains all existing functionality while improving UI layout
- Addresses UX concerns about task details taking up UI space

Fixes #5652
