fix: Resolve test collection import errors (ModuleNotFoundError)

Fixed import errors that occurred during full test suite collection:
- Error: "ModuleNotFoundError: 'empathy_os.workflows' is not a package"
- Tests passed individually but failed during full `pytest tests/` collection

Root Cause:
- Lazy loading mechanism in workflows/__init__.py using __getattr__
- Import order dependency: when tests imported workflows in different orders,
  Python's import system became confused about package vs module

Solution:
1. Added import guard in tests/conftest.py to eagerly load workflows
   - Calls discover_workflows() to trigger lazy loading of registered workflows
   - Explicitly imports non-registered workflow modules used by tests
2. Deleted Mac Finder duplicate files (" 2.py" naming pattern)

Results:
- Test collection: 6,335 tests → 13,589 tests (+7,254 tests discovered)
- Import errors: 20+ errors → 0 errors
- All workflow tests now properly discovered and collectible

Files Modified:
- tests/conftest.py: Added workflow import guard with eager loading
