- Update workonCmd to accept todo_item_title arg and add -f/--fix, -c/--complete flags
- Implement transactional flow: bootstrap todo dirs, move/create .md files, create branch, append Grok-generated Work Plan, commit
- Add todo package with Bootstrap for directory structure
- Expand workon.Run to handle modes (todo, fix, complete) with placeholders for Grok integration and optional cnadd/IDE open
Introduces the `workon` CLI command which selects the next queued todo item,
moves it to doing/, creates a git branch, generates a work plan via Grok,
appends it to the file, and commits the changes. Includes skeleton implementation
with TODOs for full functionality.
