- Approve now opens an in-app review screen showing app/user/IP/geo of the
request (optional deep-link params: app, user, ip, geo, ts) before biometrics
- Add a Deny button on the approval screen (no biometric needed to reject)
- Reject requests older than 2 min via the ts param (replay safety net)
- README: context params table, new Features bullets, approve-context screenshot
- Bump to v1.2 (versionCode 3)
