refactor: flatten CLI directory structure - remove 'box in a box'

Browse Source 
BEFORE:
/opt/aitbc/cli/
├── aitbc_cli/                    # Python package (box in a box)
│   ├── commands/
│   ├── main.py
│   └── ...
├── setup.py

AFTER:
/opt/aitbc/cli/                    # Flat structure
├── commands/                      # Direct access
├── main.py                        # Direct access
├── auth/
├── config/
├── core/
├── models/
├── utils/
├── plugins.py
└── setup.py

CHANGES MADE:
- Moved all files from aitbc_cli/ to cli/ root
- Fixed all relative imports (from . to absolute imports)
- Updated setup.py entry point: aitbc_cli.main → main
- Added CLI directory to Python path in entry script
- Simplified deployment.py to remove dependency on deleted core.deployment
- Fixed import paths in all command files
- Recreated virtual environment with new structure

BENEFITS:
- Eliminated 'box in a box' nesting
- Simpler directory structure
- Direct access to all modules
- Cleaner imports
- Easier maintenance and development
- CLI works with both 'python main.py' and 'aitbc' commands
