add zephyr3d rendering engine

[gavinyork]

Hi! 👋

I'd like to add Zephyr3D - a TypeScript rendering engine with WebGL/WebGPU support, scene graph management, and PBR rendering.

Thank you for maintaining this list!

Thanks @gavinyork, great work on Zephyr3d engine ! Could you explain what distinguish your engine compare to big ones like Three.js?

Thanks! Zephyr3D is WebGPU-first (while keeping WebGL compatibility in mind), and it’s more game-development oriented than a general-purpose 3D lib. Another key differentiator is an editor-driven workflow: efficient iteration via a visual editor (scenes/materials/assets) is a first-class goal rather than an afterthought.
