test: add integration and E2E test infrastructure

- Add pytest markers (integration, e2e, slow) with skip logic
- Add command line options (--run-integration, --run-e2e)
- Create sample_project and sample_project_with_bug fixtures
- Add test_integration.py with 10 LLM tests
- Add test_e2e.py with 12 API server tests
- Update COVERAGE.md to reflect ~65% complete
