Subject: [PATCH] Add CI: headless tests on every PR, DMG build artifact on
 main

- .github/workflows/ci.yml: macOS runner, Python 3.12, runs
  tests/test_bridge.py and tests/test_dsu.py on push/PR; builds the
  .app + DMG (uploaded as artifact) on main pushes and manual runs
- build_dmg.sh: skip `open dist` on CI (headless runner + set -e)
- README: CI badge
