 * Dispatches an execution-host descriptor to its transport-specific route
 * resolver. Shared by the runtime tunnel RPC (paired remote clients) and the
 * local direct-SSH browser route, which dials the same resolvers in-process.
 * Imports stay dynamic so the SSH stack loads only when an SSH host is used, and the
 * connection manager comes from the registry rather than `ipc/ssh` — the runtime bundles
 * this module, and `ipc/ssh` would drag Electron into a graph that must boot on plain Node.
