Subject: [PATCH] feat(primitives_gallery): wire gl_texture_load demo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tras integrar 0025 (que trajo la app entera) y 0026 (que solo añadio
demos_gl_texture.cpp + assets/sample.png + cpp/functions/gfx/gl_texture_load.*),
falta wire-up de la entrada nueva en los archivos compartidos del gallery.

- demos.h: declarar gallery::demo_gl_texture()
- main.cpp: entrada en k_demos[] con id "gl_texture", category "Gfx"
- CMakeLists.txt: añadir demos_gl_texture.cpp, gl_texture_load.cpp,
  stb_image_impl.cpp, e include dir vendor/stb
