build_zip_only.py

"""
Build ONLY the portable WinZapp.zip (onedir layout) — no MSYS2/gcc needed.

Reuses build.py's onedir pipeline but skips the C installer/uninstaller stub
compilation (compile_uninstaller / compile_installer_stub / append_zip_to_stub),
which are the only steps that require gcc/windres. The result — dist/WinZapp.zip
with the full WinZapp/ onedir layout — is exactly what the auto-updater consumes
to overwrite an existing install, so it's what we want for testing overwrite +
migration on the old version.

Picks its interpreter the same way build.py does (WINZAPP_VENV, the running
virtual environment, then venv\\ / .venv\\), so any of these work:
  venv_build\\Scripts\\python.exe build_zip_only.py
  set WINZAPP_VENV=venv_build && python build_zip_only.py
  uv run python build_zip_only.py
