Dos primitivas del pipeline de shaders_lab que ya estaban en uso pero sin indexar al registry: - code_to_generator_cpp_gfx (function, pure) Traduce un fragment shader GLSL escrito a mano (modo Code, con void main() + fragColor = ...) en un body de DAG Gen + DagControl[]. Cada uniform anotado se convierte en un control; el body usa el parametro uv y reemplaza fragColor= por return. Empaqueta uniforms en vec4 (4 x n_uniforms). - shaderlab_db_cpp_gfx (function, impure) CRUD persistente para generators custom de shaders_lab via sqlite3. Guarda el GLSL original, el body traducido para el DAG, los DagControl y los param_defaults en una BD local (shaders_lab.db). Soporta open(:memory:) para tests. Ambas se indexan ahora en registry.db y son reusables fuera de shaders_lab si en el futuro hay otra app que componga DAGs de shaders.
