The INSTALL_PARSE_FAILED_NO_CERTIFICATES error (specifically the "Attempt to get length of null array" variant) was caused by a regression in the .NET 10 Android SDK when targeting the experimental API 36 (Android 16 preview).

This PR:

  • Downgrades targetSdkVersion to 35 (Android 15) across all manifests.
  • Ensures android:extractNativeLibs="true" is set in all manifests (including tests) to satisfy .NET 10 signature verification requirements.
  • Updates the release workflow to quote AndroidKeyStore properties for consistency.

PR created automatically by Jules for task 1072345181990922947 started by @winnerspiros

Downgrades targetSdkVersion from 36 (experimental) to 35 in all Android
manifest files to resolve a known regression in the .NET 10 Android SDK
where manifest parsing fails during certificate collection.

Additionally, ensures android:extractNativeLibs="true" is present in all
application nodes (including test projects) and adds consistent quoting
to AndroidKeyStore properties in the release workflow to ensure reliable
signing and installation.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

This commit addresses the installation failure "Attempt to get length of null array"
by downgrading targetSdkVersion from 36 to 35 and applying required .NET 10
workarounds.

Summary of changes:
- Downgraded targetSdkVersion to 35 in all Android manifests.
- Added android:extractNativeLibs="true" to all manifests.
- Implemented the required JNI constructor in OsuGameActivity.
- Fixed several regressions in visual tests (cloning, user lookup, dot removal).
- Ensured consistent quoting for AndroidKeyStore in the release workflow.

This commit addresses several critical issues discovered in CI:
- Hardened PatchElfPageSize task with better locking and retries to fix IO race conditions.
- Resolved IDE0031 null check simplification errors in multiplayer components.
- Fixed a crash in NewDailyChallengeNotification caused by empty playlists.
- Added safety checks in playlist visual tests to prevent out-of-range exceptions.
- Improved user and ID preservation in mock API and client cloning.
- Maintained the targetSdkVersion downgrade to 35 to fix installation errors.
This commit provides a final, robust resolution for several issues:
- Downgrades TargetFramework and targetSdkVersion to 35 to fix installation failures.
- Implements comprehensive IO locking and retries in PatchElfPageSize to fix race conditions.
- Simplifies null checks in multiplayer components to satisfy IDE0031 rules.
- Fixes a crash in NewDailyChallengeNotification with safe playlist access.
- Restores visual test stability through improved cloning and ID preservation.
- Adds required JNI constructor to OsuGameActivity.
