Bloom engine integration with Perry UI

[tosage05]

Would be great to have native support for embedding Bloom as a widget in Perry UI, something like a BloomView that renders a Bloom scene directly inside a Perry UI app. Similar to how the project already handles webview embedding.

This would be similar to the flutter Flame game engine...

I got Codex to write a working local Linux MVP hack (Bloom renders to a shared GPU texture via Vulkan, Perry UI GTK4 imports it directly from VRAM via dmabuf).

Love it! Will make it happen soon!
