Update submodules and build config for pure WebGL 2.0 (drop -sFULL_ES3): - kicad: VBO-based drawing, compositor FBO rewrite, shader conversion - wxwidgets: Fix z-index layering so GL canvas renders above 2D UI canvas - Build: Remove FULL_ES3 from linker flags - GAL tests: White background, opaque alpha, shared shader converter, updated baseline screenshots Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
