/**
 * dispatch-host-rpc-handler — the HOST side of the ADR-0054 host-RPC upcall
 * channel (increment M4-C).
 *
 * The supervisor (`dispatch-external-tool-command.ts`) receives a worker-streamed
 * {@link HostRpcRequest} (on the transport's `progress` arm) and calls
 * {@link handleHostRpc}. This module performs the requested privileged effect
 * through the REAL host {@link ToolCliContext} — the SAME context the in-process
 * path uses (datastore via the host scope, cloud egress, FS, BaselineRepo,
 * ToolStateRepo, host planes) — and returns an {@link RpcReply} the supervisor
 * posts back to the worker via `child.send`.
 *
 * The host remains the ONLY process that performs the privileged effect. A
 * host-side fault is CAUGHT and crosses back as a structured `{ ok: false }`
 * reply (the worker shim re-throws it into the handler) — never an unhandled
 * host crash, never a silent no-op.
