## Summary Closes #12855 This PR also fixed an issue, where `python_request` was matched against `PythonVersion::Default`. Previously, if `python_request` was `3.13t`, it would match the last branch, triggering a download of the Python version if it wasn't already installed.6b7f60c1ea/crates/uv/src/commands/project/init.rs (L421-L448)```console ❯ uv init -v --managed-python --python 3.13t foo DEBUG uv 0.6.14 (a4cec56dc2025-04-09) DEBUG Searching for Python 3.13t in managed installations DEBUG Searching for managed installations at `/Users/Jo/.local/share/uv/python` DEBUG Found managed installation `cpython-3.13.1-macos-aarch64-none` DEBUG Found `cpython-3.13.1-macos-aarch64-none` at `/Users/Jo/.local/share/uv/python/cpython-3.13.1-macos-aarch64-none/bin/python3.13` (managed installations) DEBUG Skipping interpreter at `/Users/Jo/.local/share/uv/python/cpython-3.13.1-macos-aarch64-none/bin/python3.13` from managed installations: does not satisfy request `3.13t` DEBUG Skipping incompatible managed installation `cpython-3.12.8-macos-aarch64-none` DEBUG Skipping incompatible managed installation `pypy-3.11.11-macos-aarch64-none` DEBUG Requested Python not found, checking for available download...
