test: remove duplicate parseCommandLineArgs tests after rebase

- Consolidated duplicate import statements
- Removed duplicate parseCommandLineArgs test suite (lines 781-880)
- Integrated auth timeout tests into original comprehensive test suite
- Preserved setupOAuthCallbackServerWithLongPoll tests as they were new
- All 62 tests still passing with complete coverage maintained
