Foundation for the aego engine. core/ errs, log, handle arena, mathx, clock, stats platform SDL3 backend plus a headless one, input state, events gpu device abstraction with gl33 and null backends vfs scheme-based virtual filesystem with overlay mounts engine builder, module registry, phase-ordered system loop, jobs demos basic, resize, input, headless; sandbox driver OpenGL bindings are generated into gpu/gl33/gl by tools/gen-gl.sh, so the module has no external dependencies.
