feat: add project field support to TaskSamurai

Add comprehensive project field support including:
- Project column in table view with automatic width calculation
- 'J' hotkey to edit project in both table and detail views
- Project field in task detail view (between Start and Entry)
- Search functionality includes project names
- Enter key on project column allows inline editing

The project field integrates seamlessly with Taskwarrior's native
project support and follows the same UI patterns as other editable
fields in the application.
