* Add FAQ section on caching cibuildwheel's downloaded tools
Adds a Tips entry covering:
- What cibuildwheel caches (CPython/PyPy installers, virtualenv,
python-build-standalone archives) and the default per-OS cache folder.
- How to override the cache location with ``CIBW_CACHE_PATH``.
- A worked GitHub Actions example pairing ``actions/cache`` with
``CIBW_CACHE_PATH`` so the cache survives between runs.
- A pointer to ``--clean-cache`` for invalidating stale entries.
Closes#1585.
Per @joerick's request in the issue ("a caching section in the FAQ
would be great, if you can contribute it") the scope is intentionally
narrow — just FAQ-level guidance. Platform-specific caching (e.g.
Windows NuGet, addressed in #2839) lives in the platforms doc.
* docs: bump actions/cache v4 to v5
* docs: move cache to runner.temp, add cache poisoning warning (review feedback)
* fix: minor 4.0 issues in android validation, docs, and docstring
- android: raise a clear FatalError when ANDROID_API_LEVEL is not an
integer, instead of an uncaught ValueError deep in localized_vars
- docs: note that delvewheel is the default Windows repair-wheel-command
since 4.0 and how to skip it for platform-tagged wheels with no
extension module; update the now-outdated FAQ wording
- venv: fix _parse_pip_constraint_for_virtualenv docstring to say
marker-bearing constraints are evaluated against the host's default
environment (not skipped) when marker_env is None

* fix: use int() with original error for ANDROID_API_LEVEL validation
Handle ANDROID_API_LEVEL validation via try/except around int() so the
original exception message is surfaced, and so non-ASCII Unicode digits
(which isdigit() accepts but int() may reject) are handled correctly.

* fix issue on windows on Python 3.13 related to nested venvs
On win / python 3.13, virtualenv creates a venv where the 'home'
points back to the venv that sys.executable was running in, rather
than the root install. that seemingly leads to problems with package
resolution, where pip.exe couldn't find the pip python package.
this appears to fix it!
* Update constraints
* chore: revert python-discovery bump

* drop EOL manylinux images
* chore: use multi-arch manylinux images as a source for image tag
Using multi-arch images directly messes with parallel tests for now.
Using them as a source for image tag ensures that all architecture specific tags are pointing to the same tag for a given manylinux / musllinux policy.
* Apply review suggestion
