Add integration tests for run() functions to increase coverage to 83.71%

- Added integration tests for run() functions in all modules
- Tests cover main execution paths including git command interactions
- Removed problematic tests for functions that call exit() or interact with remotes
- Added tests for print functions and error handling paths
- Coverage increased from 40.24% (169/420) to 83.71% (406/485) lines
- All CI checks pass including formatting, linting, and tests
