  * Enhanced validation testing
  * Better coverage of stdio/http server types

- ProviderList.test.tsx (11 lines):
  * Updated for new card layout
  * Enhanced drag-and-drop testing

- SettingsDialog.test.tsx (96 lines):
  * Major updates for SettingsPage migration
  * New test cases for auto-launch functionality
  * Enhanced integration test coverage
  * Better async operation testing

Hook Tests:

  * Updated for refactored hook logic
  * Enhanced test coverage for edge cases

- useDragSort.test.tsx (36 lines):
  * Simplified test cases
  * Better mock implementation
  * Improved assertions

- useImportExport tests (16 lines total):
  * Updated for new error handling
  * Enhanced test coverage

- useMcpValidation.test.tsx (23 lines):

- useProviderActions.test.tsx (48 lines):
  * Extensive updates for hook refactoring
  * New test cases for provider operations
  * Enhanced mock data

- useSettings.test.tsx (12 lines):
  * New test cases for auto-launch
  * Enhanced settings state testing
  * Better async operation coverage

Integration Tests:
- App.test.tsx (41 lines):
  * Updated for new routing logic
  * Enhanced navigation testing
  * Better component integration coverage

- SettingsDialog.test.tsx (88 lines):
  * Complete rewrite for SettingsPage
  * New integration test scenarios
  * Enhanced user workflow testing

Mock Infrastructure:
- handlers.ts (117 lines):
  * Major updates for MSW handlers
  * New handlers for auto-launch commands
  * Enhanced error simulation
  * Better request/response mocking

- state.ts (37 lines):

  * New state for auto-launch
  * Enhanced state reset functionality

- tauriMocks.ts (10 lines):
  * Updated mock implementations
  * Better type safety

- server.ts & testQueryClient.ts:
  * Minor cleanup (2 lines removed)

Test Infrastructure Improvements:
- Better test isolation
- Enhanced mock data consistency
- Improved async operation testing
