update_windows.bat / update_macos.command: fetch release tags from Gitea,
move the folder to the newest vX.Y (git downloads only what changed),
connect a folder unpacked from a release zip on first run, install git/uv
when missing and sync the Python libraries. Developer copies on a branch
are left alone.
run_* and update_* share one environment (KotaTechnicianTool/venv)
instead of one per version.
