HMS MediaEngine Agent
362e089be0
Der Nutzer hat recht: Der Ordner war voller Entwicklungs-Muell. Jetzt ist sauber getrennt: ROOT (was der Nutzer sieht und braucht): - run.py = das Programm - hms_app/ = der Anwendungscode - HMS MediaEngine.app = macOS Doppelklick-Starter - HMS-Start.vbs = Windows Doppelklick-Starter - HMS-Install.vbs = Windows Erst-Installation - HMS-Mac-Install.command = macOS Homebrew-Installation - HMS-Portable-Install.command = macOS Portable-Installation (16GB-Fix) - installer_gui.py = grafischer Installer - launcher.pyw + launcher_core.py = interne Start-Logik - LIESMICH.txt = 10-Zeilen-Kurzanleitung - .gitignore _entwicklung/ (alles andere, NICHT benoetigt): - packages/ apps/ native/ plugins/ tools/ schemas/ tests/ docs/ build/ fixture_profiles/ - PLAN.md STATUS.md ERRORS.md TEST_REPORT.md CHANGELOG.md README.md - pyproject.toml uv.lock setup_*.sh/ps1 make_mac_app.py Diese Trennung gilt ab sofort fuer alle Commits. Der Nutzer kann _entwicklung/ loeschen wenn er Platz braucht - die App laeuft ohne. Verifiziert: App startet nach Aufraeumen unveraendert (Health 200).
