Delegate Click commands via subprocess instead of direct import

- Changed Click command delegation from importing aitbc_click() to subprocess call
- Runs click_cli.py as separate process using sys.executable
- Passes through command line arguments via sys.argv[1:]
- Returns subprocess exit code to caller
