How to test

1. Push a branch or open a pull request to trigger the GitHub Actions workflow.
2. Verify the App Compile job successfully builds the standard debug APK.
3. Download the standard-debug-apk artifact from the workflow run and verify the APK installs successfully.

Greptile Summary

This PR extends the app-compile CI job to run a full assembleDebug build and upload the resulting APKs (standard and fdroid flavor) as GitHub Actions artifacts with a 7-day retention window.

• Adds ./gradlew :app:assembleDebug after the existing Kotlin-only compile check, then uploads both flavor APKs via actions/upload-artifact@v4.
• Neither upload step sets if-no-files-found, so a path mismatch would produce an empty artifact and a green workflow rather than a visible failure.

Confidence Score: 5/5

Safe to merge — the change only adds artifact upload steps to an existing CI job with no impact on app code or test logic.

The change is additive and isolated to CI configuration. The new build and upload steps do not affect any application code, and the existing compile and test jobs are untouched. The only notable gap is that missing APK files would produce a silent warning rather than a job failure, which is a CI hygiene concern but not a blocking defect.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/test.yml	Adds assembleDebug build step and two APK artifact uploads (standard + fdroid flavors) to the app-compile job; artifact upload steps use the default if-no-files-found: warn which silently succeeds on missing files, and the existing 10-minute timeout may be too tight for a full APK build.
