/**
 * 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.
 *
 * Authored channels receive `RouteHandlerArgs`; framework-internal channels
 * receive the smaller `RouteContext` used by callback routes.
