- Update Python version requirement from 3.8+ to 3.10+ across badges,

- Move imports to module level in all *_core.py test files (16 files)
- Remove try/except/skip patterns from integration tests
- Remove @pytest.mark.skip decorators from gradient flow tests
- Convert environment validation skips to warnings for optional checks
- Change milestone tests from skip to fail when scripts missing
Tests now either pass or fail - no silent skipping that hides issues.
This ensures the test suite provides accurate feedback about what works.
Remove the doctor/health alias duplication in favor of a single
'tito system health' command for environment validation.
