Upgrade youtubei.js to 16.0.1 and fix downloader plugin

[Copilot]

Ports pear-devs#4069 to fix the downloader plugin for youtubei.js v16, which deprecated the player_id configuration in favor of signature function evaluation via Platform.shim.eval.

Changes

• package.json: Upgrade youtubei.js 15.0.1 → ^16.0.1
• pnpm-lock.yaml: Update transitive dependencies (jintr → meriyah, @bufbuild/protobuf → 2.6.3)
• src/plugins/downloader/main/index.ts:
  • Import Platform from youtubei.js
  • Add Platform.shim.eval handler before Innertube.create()
  • Remove hardcoded player_id: '0004de42' from config

Example

// Set up Platform shim for signature function evaluation
Platform.shim.eval = (code: string) => {
  // eslint-disable-next-line @typescript-eslint/no-unsafe-return
  return eval(code);
};

yt = await Innertube.create({
  cache: new UniversalCache(false),
  // player_id removed - now handled by Platform.shim.eval
  cookie: await getCookieFromWindow(win),
  generate_session_locally: true,
  fetch: getNetFetchAsFetch(),
});
