macOS Harness

Use one CLI call per decision point, not per primitive:

macos-harness <<'PY'
app = "Spotify"
mac.see(app)
mac.key("cmd+k", app=app)
mac.type("Alessia Cara", app=app)
print(mac.see(app))
PY

The CLI preloads mac, browser, Path, and subprocess. Prefer bounded stdin programs; reserve macos-harness repl for manual exploration and always exit it.

Minimize round trips
