feat!: export types from main entry and remove /types export

What is the purpose of this pull request?

In this PR, I've exported all types from src/types.ts through the main entry point and removed /types export.

I've followed the same pattern as in eslint/json#198 and this PR aligns with the approach used in the Markdown repository in eslint/markdown#520 and eslint/markdown#564.

Previously, to access the global types defined in src/types.ts, they had to be imported from @eslint/css/types. After this change, they can be imported directly from @eslint/css.

Also, I've removed the /types export, since the types are now re-exported by the main entry point.

What changes did you make? (Give an overview)

To enable importing types from the main entry point, I used a small trick.

The types.ts file is built into types.js and types.d.ts.

In the built types.js, it's possible to re-export the type declarations from the main entry point using export * from "types.js".

However, that wasn't possible in the source. To bridge the gap, I added a dummy src/types.js file so types can be imported from src/types.ts.

Pull request overview

This PR refactors the type exports to make all types available from the main entry point (@eslint/css) instead of requiring a separate import path (@eslint/css/types). This improves the developer experience by consolidating imports and aligns with the patterns established in the eslint/json and eslint/markdown repositories.

Changes:

• Added export * from "./types.js" to the main index.js file to re-export type definitions
• Created a dummy src/types.js file to enable type imports in the source code (works around TypeScript import resolution)
• Removed the ./types export path from package.json
• Updated test file to import types directly from @eslint/css instead of @eslint/css/types
