fix: remove original EffectTextureMaker app code, clarify licensing

Remove fxgen.module.min.js and classic.html — original mebiusbox app
code with no clear open-source license. ShaderBrew only depends on
pixy.js (MIT licensed) which remains.

Updated all credits/docs to accurately reflect: pixy.js shader library
is MIT by mebiusbox, everything else is original ShaderBrew code.

 ## Gotchas
-- `s` (fxgen app object) is module-private — not accessible from outside
 - Gallery uses IntersectionObserver + round-robin (max 6/frame) for GPU efficiency
 - Puppeteer needs Xvfb for WebGL: `xvfb-run --auto-servernum node save-sprites.mjs`
 - Custom shaders NOT in editor yet — only in sprite gallery. Editor uses pixy effects only.

 ## Credits
 
-Built on [EffectTextureMaker](https://mebiusbox.github.io/contents/EffectTextureMaker/) by [mebiusbox](https://github.com/mebiusbox) (MIT License). The original tool provides the core procedural shader library (pixy) and single-layer editor.
+Uses [pixy.js](https://github.com/mebiusbox/pixy.js) by [mebiusbox](https://github.com/mebiusbox) (MIT License) — the procedural shader library that powers the 65+ built-in effect types.
 
-ShaderBrew adds multi-layer compositing, gradient mapping, PBR generation, 3D preview, 52 custom GLSL shaders, sprite sheet generation, the showcase, material forge, and the enhanced editor UI.
+Everything else (editor, layers, compositing, gradient mapping, PBR generation, 3D preview, 52 custom GLSL shaders, sprite sheets, showcase, material forge) is original ShaderBrew code.
