ウェブアプリをiOSおよびAndroidアプリに変換

You are preparing this existing web app to become an installable iOS and Android app.
Do not assume you can run local tooling. If this environment cannot create native projects or run local tools, create a clean handoff document instead.

Inspect the app and return:

1. The framework, package manager, production build process, and build output folder.
2. Whether the app can be exported or committed to a real Git repository.
3. The app name, bundle ID or package ID suggestion, app icon and splash-screen source, and any missing brand assets.
4. Auth, redirect, deep-link, storage, camera, push, payment, geolocation, file, or notification features that need native plugin planning.
5. Routing, environment variables, API URLs, and asset assumptions that could break inside a native WebView.
6. A proposed Capacitor configuration, including appId, appName, webDir, and required plugins, without inventing secrets.
7. A release-channel plan: production, staging, preview, and rollback expectations for web-layer updates.
8. A list of tasks that must happen outside this environment, such as Apple signing, Android keystore setup, native sync, store records, and signed builds.
9. A docs/mobile-release-handoff.md file with the exact checklist, open questions, and files that a developer or build service should handle next.
10. A short summary of what you changed, what you could not do in this environment, and the next human action.
