Minor Changes - BREAKING CHANGE: Middleware must now explicitly continue the request chain by calling `next()` or return a `Response`. The router no longer calls `next()` automatically when middleware returns `undefined`; instead, it throws an error to catch missing continuation bugs early. Middleware that only mutates context should return the downstream response: ```ts // Before function loadUser(): Middleware { return (context) => { context.set(CurrentUser, user) } } // After function loadUser(): Middleware { return (context, next) => { context.set(CurrentUser, user) return next() } } ``` Middleware that needs to inspect or modify the downstream response should `await next()` and return a `Response`: ```ts function logger(): Middleware { return async (context, next) => { let response = await next() console.log(context.request.url, response.status) return response } } ``` - Add `router.mount()` and the `RouteBuilder`/`RouteInstaller` types so route groups can be written as local, reusable pieces of an app instead of hard-coding the full URL where they happen to live today. A route installer receives a prefixed route builder that can register routes with the same `route()`, `map()`, and method helpers as a router, while the parent router remains responsible for dispatch, matching, middleware, and default 404 handling. Before `router.mount()`, route groups that lived in separ
