First release prepared for F-Droid.

- Single universal APK replaces the five per-ABI APKs (the app has no
  native code, so they were identical in size anyway).
- Play-Store dependency-info blob removed from the APK.
- App-store metadata (descriptions, screenshots, icon) now ships in the
  repository under fastlane/.
- Jio/Vi plan-expiry notices are treated as important recharge reminders
  instead of promotions.
