What changed?

The "Add to Obtainium" link pointed at https://apps.obtainium.imranr.dev/redirect?r=..., which doesn't exist — that domain is Obtainium's crowdsourced app-config site, not a redirect service, and reported "Invalid URL. Redirect should start with obtainium://" when tapped.

Fixed it to use Obtainium's actual deep link scheme, obtainium://add?url=<encoded-source-url>, confirmed against Obtainium's own AndroidManifest.xml (intent filter for the obtainium scheme) and its handler in lib/pages/home.dart (reads the source URL from the url= query param on an add host). Also fixed the identical broken link on the live v5.1 GitHub release notes directly.

How was it checked?

• Verified the correct scheme against Obtainium's public source (manifest + deep link handler), not guessed.
• Known limitations: not tested against the actual Obtainium app on a device (no APK install step here); the fix matches the app's own parsing code exactly.
