The GUI embeds its shaders' GLSL from shaders/ always: the 14 prebuilt copies, identical to their sources, go, and so does the label saying which was used

shaders/prebuilt/*.glsl were byte-identical to shaders/X.glsl or to prefix.glsl + post/X.glsl (checked with cmp, all 14), kept only so a -Dprebuilt-shaders build could name them; EffectCode and Config then labelled the GUI's shader source as live or prebuilt. The GUI embeds shaderSource (a concatenation, no glslc) either way now; the prebuilt SPIR-V stays, and zig build shaders refreshes only it. Config's report and EffectCode lose their GUI shader source line.
