Adds --body as a hidden alias for --description in create/update commands,
following GitHub CLI convention for better agent ergonomics.
The --body flag:
- Works alongside existing --description and -d flags
- Hidden from help output to avoid clutter
- Validates conflicts when both flags used with different values
- Available in both 'bd create' and 'bd update' commands
