## Summary
Adds regular expression based version filter to python mirror script.
## Test Plan
Manually using `uv run ./scripts/create-python-mirror.py --name cpython
--arch x86_64 --os linux --version "3.13.\d+$"`
## Summary
The architecture details in `crates/uv-python/download-metadata.json` is
now a dictionary with family and variant data, whereas it used to be a
string. This patches the architecture filter in
`scripts/create-python-mirror.py` to support both scenarios.
## Test Plan
Tested manually using `uv run ./scripts/create-python-mirror.py --name
cpython --arch x86_64 --os linux --from-all-history`
## Summary
I added `crates/uv-python/create-mirror.py` to make it easy to download
all the needed files to create a mirror for Python distributions in an
offline environment.
the script also has an option to iterate over the git history of the
`download-metadata.json` to make sure we have all the files needed for
all the uv versions
## Test Plan
```
uv run create-mirror.py --from-all-history --os linux --arch x86_64 --name cpython

now you can run UV_PYTHON_INSTALL_MIRROR='file:///home/meitar/dev/uv/crates/uv-python/mirror' uv python install
```
then checked (the `unshare` command make sure that the process don't
have any netwok)
```
UV_PYTHON_INSTALL_MIRROR=file:///home/meitar/dev/uv/crates/uv-python/mirror sudo -E unshare -n /home/meitar/.local/bin/uv python install 3.13
