Vk.heap_bytes pulled the Vk module - and on lang/uifree the GL window path - into a plain program, which then failed to link (_cgl_offscreen, lgl_GetError). Os.heap_bytes is malloc_zone_statistics through a weak reference (0 where there is none, and on Windows). Reseeded. Docs for it and for Json.free / Json.free_all.

The bytes malloc holds live across every zone of the process, on macOS; 0 on other platforms. Ludic has no garbage collector, so a path that runs every frame must give back all it takes: read this before and after many rounds of it, and the difference is what it keeps. A test built on it should allow for 0 elsewhere.
