sokol_setup

Helpers minimos para usar sokol_gfx con SDL3 sin depender de sokol_glue.h (que importa simbolos de sokol_app y rompe en stacks SDL3-driven).

Definidos como funciones puras: solo construyen structs, no tocan estado global. Llamadas tipicas en engine_smoke (issue 0072a) y runtime_test (0072b).
