Procedural cloud layer below the floating island #256

New Issue

GLSL undefined variables — the fragment shader referenced JS variables (CLOUD_LAYER_Y, CLOUD_THICKNESS, CLOUD_OPACITY) as plain GLSL identifiers. They are undefined in GLSL scope, causing shader compilation failure. Fixed by interpolating their values into the template literal with ${...}.
Broken simplex noise — the snoise() implementation had incorrect x_/y_ rescaling, wrong a0/a1 gradient coefficient formula, and transposed p0–p3 swizzles. Replaced with the canonical Ian McEwan / Stefan Gustavson implementation.

PR created: http://143.198.27.163:3000/Timmy_Foundation/the-nexus/pulls/339 Fixed two bugs that prevented the cloud layer from rendering: 1. **GLSL undefined variables** — the fragment shader referenced JS variables (`CLOUD_LAYER_Y`, `CLOUD_THICKNESS`, `CLOUD_OPACITY`) as plain GLSL identifiers. They are undefined in GLSL scope, causing shader compilation failure. Fixed by interpolating their values into the template literal with `${...}`. 2. **Broken simplex noise** — the `snoise()` implementation had incorrect `x_`/`y_` rescaling, wrong `a0`/`a1` gradient coefficient formula, and transposed `p0`–`p3` swizzles. Replaced with the canonical Ian McEwan / Stefan Gustavson implementation.
