`c.req.valid` does not work in route without path

[yusukebe]

What version of Hono are you using?

4.4.7

What runtime/platform is your app running on?

any

What steps can reproduce the bug?

const app = new Hono()

app
  .get('/', (c) => {
    return c.json(0)
  })
  .post(
    validator('json', () => {
      return {
        foo: 'bar',
      }
    }),
    (c) => {
      const foo = c.req.valid('json')
      return c.json(1)
    }
  )

What is the expected behavior?

It does not throw a type error.

What do you see instead?

Additional information

This will be fixed when changing the order for overloading in HandlerInterface.
