Cozy: Just Shader

Added Minecraft 1.16.5, 1.18.2, and 1.19.2 builds for Fabric and Forge. Updated all previous builds to 1.4.0 — 16 expansion JARs in total. Added the “>10 FPS — Extreme” preset with 8192×8192 shadows and enhanced effects. Fixed color values, preset resets, and settings application on older Forge versions. Passed 4,752 shader compilation checks and 28 Forge tests; in-game behavior and FPS remain untested.
