fn dispatch_command(world: &World, command: McpCommand)Expand description
Run one MCP command against the world it names.
A command for a world the host merely carries is queued as a command of
the host’s own, because only the host’s thread may touch its world. The
list names every world a tool can reach: the host’s own, each nested
world an entity carries, and each world an entity holds a
WorldSender for — a world on a thread of its own or one the host
steps, neither of which a nested-world lookup could find.
