This looks good! just some conflicts to resolve and I think we can merge it!

You can disable this rule entirely for this package in the eslint.config.js file of packages/env because it won't ever work as that the turbo plugin wouldn't be able to see the turbo.json files of the apps, where these env vars are passed through.

Add this to packages/env/eslint.config.js:

import { configs, defineConfig } from '@orbitkit/eslint';

export default defineConfig(...configs.base, {
  rules: {
    // We disable this rule in this package because turbo can't find the turbo.json files of the apps to know that we are actually passing through env vars there.
    'turbo/no-undeclared-env-vars': 'off',
  },
});

Then you can remove the eslint-disable-next-line comments from this file.
