Type Alias CommandShadowHook

CommandShadowHook: (
    host: Stuff,
    shadow: Shadow,
    op: "attach" | "detach",
) => void

The command-recency-stack delta a shadow attach/detach drives. Implemented by CommandApi.applyShadowDelta, injected via ShadowApi._registerCommandShadowHook so the shadow subsystem doesn't statically import command (a layering inversion that would pull the whole command closure onto the boot path).
