Generate custom shader effects from a text prompt

I added a Shaders panel to the editor: describe an effect in a text prompt and it generates a custom GLSL shader for it, the same way Figma’s shader tool works. It ships with a library of built-in presets too — pixelate, halftone, chromatic aberration, scanlines, dithering, and others — to start from or use as-is.

Anything the prompt generates can be edited by hand afterward in a code view, saved, and reused across layers or the whole canvas. It’s meant for the one-off looks a slider-based effects list can’t cover.
