Bug Timeline:
═════════════

BEFORE (Broken):
  notification_options=None
         ↓
  get_capabilities(None, None)
         ↓
  AttributeError: 'NoneType' object has no attribute '...'
         ↓
  ❌ Server fails to start

AFTER (Fixed):
  notification_options=NotificationOptions()
         ↓
  get_capabilities(NotificationOptions(), {})
         ↓
  ✅ Server starts successfully

Test Protection:
  test_no_attribute_error_during_initialization
         ↓
  Verifies no AttributeError is raised
         ↓
  ✅ Regression prevented
