feat: redesign Brainy CLI for intuitive UX and add Brain Jar support

- Refactor CLI to use direct commands instead of nested structure
- Add Brain Jar AI coordination commands with premium/free modes
- Update Cortex class with enhanced Brain Jar functionality
- Fix TypeScript compilation by removing exclusion of cortex directory
- Improve user experience with beautiful branded output
- Add comprehensive help system and backward compatibility

Major UX improvements:
- brainy init, add, search (direct commands)
- brainy install brain-jar (simple installation)
- brainy brain-jar start/dashboard/status (rich subcommands)
- brainy chat (interactive mode)
- brainy config set/get/list (configuration management)

This redesign makes Brainy significantly more user-friendly while
maintaining all existing functionality and adding powerful new
AI coordination capabilities.
