Fix type checking issues

- Add type ignore comments for intentional test errors in Agent() constructor calls
- Fix callable check for create_claude_session function
- Replace LocalGitRepo method calls with direct git CLI operations in agent_detail.py
- Add try/except blocks around SDK imports with fallback behavior in language.py and pr_review.py

This addresses multiple type checking diagnostics including:
- Missing argument errors in tests
- Call non-callable errors
- Unresolved attribute errors
- Unresolved import errors for SDK modules
