actions/setup-python@v5 hangs inside its Windows tool-cache install script on
the self-hosted runner. Replace it with an "Ensure Python 3.11" step that uses
an existing py -3.11 / PATH python if present, otherwise silently installs
Python per-user (no elevation, cannot prompt). Invoke pip/PyInstaller via the
resolved interpreter path, and add a 30-minute job timeout so a hang can no
longer run indefinitely.
