* feat: add CPython 3.15 support for iOS

* fix: skip directories when copying iOS support files
When copying multiarch-specific support files (e.g. _cross_arm64_iphoneos.py),
the code was trying to copy all items in the directory including __pycache__
directories. The shutil.copy() function only works with files, not directories,
which caused an IsADirectoryError.
This fix adds a check to only copy files, skipping any directories like
__pycache__ that may have been created by Python imports.

* Ensure target Python directory exists before build
Add assertion to check if target Python directory exists.
* fix(ios): use stdlib dir directly instead of copying to platform-config
Remove the _inject_support_files workaround for python.org 3.15+
distributions. Instead of copying sysconfig files from the stdlib into
a synthetic platform-config/ directory, pass the stdlib directory
directly to make_cross_venv.py.
make_cross_venv.py is updated to derive the multiarch tag from the
_sysconfigdata_ filename rather than assuming it comes from the
directory name.

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!

* Fix the PATH mangling in action.yml
Let's put the `uv` on PATH question aside, and fix#2663.
This change ensures that the PATH entries added by Github when you request `shell: bash` don't make it into the pwsh environment. It also keeps the uv binary on PATH if installed via `extras:`.
Would love to get this fixed soon, then we can figure out the right approach regarding `uv` discovery.
* Modify script to allow testing of the GHA action on a PR
Cherry-picked from #2718 and modified so we can test the action.yml file
pypa/manylinux now has a manylinux_2_35_armv7l image allowing for better C++20 support.
piwheels is still building for Debian Bullseye so keeping manylinux_2_31 as the default image.
