feat: add forMiddleware types to Input

[nakasyou]

I added a forMiddleware prop to Input.
In WebSocket helper, helper uses json property for telling data to client, but I think it isn't smart because websocket helper actually doesn't use JSON.

This PR adds properties for various helpers and middleware to tell data to clients.

In creating this PR, I enabled that ToSchema receives Input instead of Input['in'].

Author should do the followings, if applicable

• Add tests
• Run tests
• yarn denoify to generate files for Deno

Hi @nakasyou !

This is an interesting feature. Please let us know another use case, not only the WebSocket helper case.

For example, you can create your protocol such as type-safe SSE:

// server
import { typedSSE, sseClient } from 'hono-typed-sse'
import { Hono } from 'hono'
import { hc } from 'hono/client'

const app = new Hono().get('/sse', typedSSE<Data>(...))

// client
const client = hc<typeof app>('/')

const sse = sseClient(client.sse)

In this case, this package can use forMiddleware namespace.

Cool! I'll use it to know the feeling of using it.

Hi @nakasyou

Sorry for the delay. This is good. We can merge this.

But one thing. I wonder if the naming forMiddleware is not so good because it's not just for middleware; we have to name it with a more general name. My suggestion is stash. There are other words, but stash is proper to mean temporary places to store the types.

Any thoughts?

Hi @yusukebe, thank you for trying.

I agreed. I think so. So I changed.

Also, I changed stash from unknown to Record<string, unknown>

Thank you!

However, we have other very interesting PRs. I'll consider merging this feature with them.

Anyway, can you see #2581 ?
