Init the socket:test/context automatically on import { test } from 'socket:test'

[chicoxyzzy]

This way we don't have to remember to import the context. This will also allow us to do --test=./test/module.js to run only one test at time instead of commenting all the other module imports in the ./test/index.js

...or even group modules like this

/test
  /dom
    dom-test1.js
    dom-test2.js
  /something-else
    module1.js
    module2.js
  dom.js
  something-else.js
  index.js

where index.js is:

import './dom.js'
import './something-else.js'

There should be a check that context is only initialized once

When it's done, we need to update tests in the socket-examples (if there're any) and templates in the create-socket-app (TODO: think how it can work with vite templates)
