Patch python-virtualenv for CVE-2026-24049 [Medium]

• Patch modified: Yes
• docs/news.rst and tests/commands/test_unpack.py files are not present in python-virtualenv source tarball, so patch didn't apply for these two files.
• Astrolabe patch reference: https://github.com/pypa/wheel/commit/7a7d2de96b22a9adf9208afcc9547e1001569fef.patch

Patch python-virtualenv for CVE-2026-1703 [Low]

• Patch modified: Yes
• tests/unit/test_utils_unpacking.py file is not present in python-virtualenv source tar ball, so patch didn't apply.
• In pip-25.3-py3-none-any.whl the news/+1ee322a1.bugfix.rst new path is not added from upstream patch to maintain compatibility with existing virtualenv cleanup behavior after tightening path validation logic (commonpath). This avoids leaving non-runtime artifacts in site-packages during pip uninstall and allows existing tests to pass without modifying test code.
• Astrolabe patch reference: https://github.com/pypa/pip/commit/8e227a9be4faa9594e05d02ca05a413a2a4e7735.patch
