Sebastian Krüger 4b4c23d16e fix: use venv Python directly instead of source activation
- Change from 'source venv/bin/activate' to direct venv/bin/python execution
- Use exec to replace shell process with Python process
- Fixes issue where supervisor doesn't properly activate venv
- Ensures all extension dependencies are available
