`usePathname()` still returns string even with Typed Routes enabled

https://codesandbox.io/p/sandbox/github/vercel/next.js/tree/canary/examples/reproduction-template

To Reproduce

1. Enable typed routes in next.config.js:

   // next.config.js
   module.exports = {
     experimental: {
       typedRoutes: true,
     },
   }

2. Use usePathname() in a Client Component:

   'use client'
   import { usePathname } from 'next/navigation'
   import type { Route } from 'next'
   
   export default function Example() {
     const pathname = usePathname()
     const go = (p: Route) => {/* ... */}
     // Type error (pathname is string):
     // Argument of type 'string' is not assignable to parameter of type 'Route'.
     go(pathname)
     return null
   }

Current vs. Expected behavior

Expected Behavior

• With typed routes enabled, usePathname() should return Route (or a branded equivalent), or
• Provide a new hook (e.g., useTypedPathname() / useCurrentRoute()) or a helper/guard (e.g., asRoute(pathname)) to safely narrow the type at compile time.

Actual Behavior

• usePathname() returns string, forcing unsafe casts and losing the refactor safety that Typed Routes aims to provide.

Additional context

When typedRoutes: true is enabled, Link and router.push/replace become type-safe (Route). However, usePathname() still returns string. Shouldn’t it return Route (or provide a typed alternative) to keep parity with Typed Routes?
