/**
* Create a middleware factory that wires Permix into Elysia routes.
*
* Use `.contextKey('name')` to set a custom context key (defaults to a unique
* `Symbol('permix')`).
*
* @example
* ```ts
* import { Elysia } from 'elysia'
* import { createPermix } from 'permix/elysia'
*
* const permix = createPermix<{
*   post: ['create', 'read']
* }>()
*
* new Elysia()
*   .onBeforeHandle(permix.setupMiddleware(({ context }) => ({
*     post: { create: true, read: true },
*   })))
*   .onBeforeHandle('/posts', permix.checkMiddleware('post.read'))
*   .get('/posts', () => ({ ok: true }))
*   .listen(3000)
* ```
