Summary of Changes

Hello @aignas, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses the need for functional testing of .pth files within virtual environments, as identified in issues #3340 and #3339. It introduces a new test case that ensures Python modules specified through .pth files are correctly discovered and importable when virtual environment site packages are active, thereby enhancing the robustness of the virtual environment management.

Highlights

• New Functional Test for .pth Files: A new functional test has been introduced to verify the correct handling and import of modules defined via .pth files within virtual environments.
• Expanded Test Coverage: The existing py_reconfig_test now includes a new py_library dependency, nested_with_pth, which specifically uses a .pth file to define a module path.
• Test Assertion Added: The bin.py test file has been updated to assert that the nested_with_pth module can be successfully imported when venvs_site_packages is enabled, confirming .pth file functionality.

Code Review

This pull request adds a functional test for .pth file handling in venvs, which is a great addition. The test setup is correct and covers the intended scenario. I've suggested a couple of minor improvements to make the test more robust by adding content to the test module and asserting it, which is a pattern used in other tests in this file. Otherwise, the changes look good.
