map packs: Fs.mount / Fs.unmount at run time, and a map's bakes under assets/baked/maps/<map>/

Browse source 
Maps ship outside the game, each one a content-addressed pack (.lmap: the .lpak format) downloaded to
the save root. The runtime already served reads from packs mounted at boot (packs.index); now one can
come and go while the game runs:

- Fs.mount(path) -> bool maps a pack over the ones mounted before it (searched first, as a later
  packs.index line is); Fs.unmount(path) -> bool gives the mapping back (munmap, UnmapViewOfFile on
  Windows) and closes the gap in the search order. Each slot keeps its length and path for it. A
  FILE* still open over one of its entries (a baked_open_range) is closed first. Still 8 packs at most.
- baked_path(map, file) is assets/baked/maps/<map>/<file> for a map's bake - what its .lmap carries
  and the game's own pack never does - and assets/baked/<file> for the rest.

The IR assembles for macOS and Windows (llvm-as). Compile-only: nothing mounted or run here.
