llimphi-wasm-runner

The host side of Tier 3 WASM apps.

WasmGuest loads a .wasm following the llimphi-wasm-app-sdk ABI, instantiates it with wasmi and runs its Elm loop:

  1. wasm_init builds the guest's Model (it lives in the instance).
  2. wasm_view returns a serialized WireNode; we deserialize and cache it.
  3. wire_to_view materializes it into a real Llimphi View<RunnerMsg>.
  4. A click emits RunnerMsg::Guest(bytes); WasmGuest::dispatch bounces those bytes back to wasm_dispatch and refreshes the view.

The host keeps a single live Store per app, so the Model persists between frames — exactly Llimphi's Elm contract, only with the transition running on the other side of the WASM boundary.

It is the Linux-side twin of wawa's WASM app executor (sys_render_frame + capabilities by physical boundary): the same spirit, another host.
