Shared test fixtures for pytest.

This file defines reusable fixtures that are automatically discovered by pytest
and can be used across multiple test modules.

Fixtures:
---------
- local_tmp_path: Creates (or cleans) a temporary directory under 'tests/tmp'
  to store output files generated during tests. Ensures a clean environment
  for each test run.
