// factory on coderd.API.AIBridgeTransportFactory at startup so callers route
// traffic through the daemon without going through the gated HTTP route.
// The returned RoundTripper is responsible for adapting the caller's request
// to the aibridge daemon's mount path: callers hand it an upstream-shaped
// request and the transport rewrites URL.Path to "/api/v2/ai-gateway/<name>/..."
// before dispatching. Routing keys on the provider's instance name so callers
// can use the same string the proxy daemon and the bridge mount use.
// Source is informational: implementations must not gate on it. It is attached
// to the request context so handlers can include it in logs and metrics.
