/**
 * WebSocket adapter for Bun runtime.
 *
 * On Node.js, the RCS server uses @hono/node-ws which creates upgradeWebSocket
 * via createNodeWebSocket({ app }). The Node entry passes it to registerRoutes().
 *
 * Route modules (session-ingress, acp) accept upgradeWebSocket as a factory
 * parameter so they work with either adapter.
