[edgarrmondragon]

Summary by Sourcery

Introduce pytest markers for Singer SDK built-in tests, enabling granular test selection and updating documentation, project templates, and CI workflows to support the new markers.

New Features:

• Add pytest markers singer_stream and singer_stream_attribute to auto-generated tests

Enhancements:

• Apply markers automatically in pytest_generate_tests for BaseTestClass subclasses
• Annotate sync_all methods with override decorator in testing runners
• Refine BaseTestClass.params type annotation to list of parameter mappings

Build:

• Include packages/** path in test and CodeQL workflows
• Add pytest.ini marker definitions and addopts to cookiecutter and root pyproject.toml

CI:

• Update GitHub test workflow to include packages/** in paths

Documentation:

• Add Pytest Markers section with usage examples and benefits in testing documentation
