📚 Description

This PR adds support for the satisfies keyword when it's used in Vite configs. Specifically for the case, when a config object is declared as a variable (with satisfies) before it's exported:

import { somePlugin1, somePlugin2 } from 'some-module'

import type { UserConfig } from 'vite';

const myConfig = defineConfig({
  plugins: [somePlugin1(), somePlugin2()]
}) satisfies UserConfig;

export default myConfig;

I also added support for using satisfies in conjuction with defineConfig but I'd argue this is pretty unlikely to be used, so happy to remove if reviewers would prefer that.

That's weird, ideally, it should have already been forwarded by

magicast/src/proxy/proxify.ts

Line 48 in a8752c8

case "TSSatisfiesExpression": {

Oh I see, it's direct AST manipulation. I think ideally we better call proxify to generate subtree so magicast could handle them automatically, and we don't need to do code generation and parsing again in the helpers. I am fine with having this for now.
