/**
 * Dispatches one channel request identified by `routeKey`.
 *
 * Each channel route is mounted as its own virtual Nitro handler with the
 * route key and artifacts config baked in. Nitro's router matches the URL
 * and populates `event.context.params`, so no custom URL matching is
 * needed — the handler looks up the channel by its `(method, urlPath)` key
 * directly. When routes register background work through `ctx.waitUntil`,
 * Nitro forwards that work to `event.waitUntil()` so webhook
 * acknowledgements can return immediately.
 *
 * Two dispatch shapes: authored channels (`defineChannel` and its
 * wrappers) carry a `handler` field and receive `RouteHandlerArgs` with
 * `send`, `getSession`, etc. Framework-internal channels (the
 * connection callback route) build `ResolvedChannelDefinition` directly
 * with just `fetch` and receive a `RouteContext` carrying `agent`.
