Walkthrough

Context parameter propagation through server route handling: handleServerRoutes now accepts and forwards a context: any argument through the middleware chain to executeRouter and executeMiddleware, replacing the previous empty object default.

Context propagation in server route handling packages/start-server-core/src/createStartHandler.ts	Add context: any parameter to handleServerRoutes function; propagate context through middleware chain and executeRouter instead of passing empty object; update call sites to pass context when invoking handleServerRoutes

Poem

🐰 Through channels of routing, I hop and I bound,
Passing context along without a sound,
Middleware threads now catch every frame,
Context flows freely—no more empty shame! 🎉

packages/start-server-core/src/createStartHandler.ts (2)

243-248: LGTM: Context propagation to server routes.

The context is correctly threaded from the outer middleware chain to the server route handler, enabling server routes to access the context established by global middlewares.

---

414-419: LGTM: Context properly threaded through inner middleware.

The context is correctly passed to the inner executeMiddleware call, which ensures it flows through route-specific middlewares and handlers, ultimately reaching the router execution.
