Enables Vulkan support across all platforms by removing the renderer filter and restores critical Android JNI surface handling to prevent initialization crashes.

Key changes:

  • Modified RendererSettings.cs to include Vulkan in the available renderers.
  • Updated OsuGameActivity.cs with GetSurfaceGlobalRef and surface discovery logic, ensuring a valid JNI reference is available for the background rendering thread.
  • Added native library loading for 'osu_native' to support the existing Vulkan probe.
  • Confirmed renderer switching triggers a clean app restart.

- Enabled Vulkan in RendererSettings.cs for all platforms by removing the manual filter.
- Restored robust Android Vulkan surface handling in OsuGameActivity.cs:
    - Added GetSurface() and findSurfaceView() to locate the rendering SurfaceView.
    - Added GetSurfaceGlobalRef() to create a JNI Global Reference on the UI thread, preventing threading violations during Vulkan initialization.
- Added explicit loading of the 'osu_native' library in OsuGameActivity.cs for the Vulkan probe.
- Verified that renderer switching triggers a clean app restart.

👋 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!
