Archive epb-ts-example repo and add examples folder to monorepo

[javierbrea]

Summary

The standalone repository javierbrea/epb-ts-example was created as a reference for using eslint-plugin-boundaries with TypeScript. Since the project has migrated to a monorepo structure, maintaining a separate example repository introduces overhead and risks becoming (further) outdated.

Proposed Changes

• Add an examples/ folder to this monorepo containing setup examples for different use cases, starting with a TypeScript example (migrating the content of epb-ts-example).
• Archive javierbrea/epb-ts-example once the TypeScript example has been moved here, pointing users to the new location.
• Update the TypeScript Support documentation at jsboundaries.dev/docs/guides/typescript-support to link to the new examples/ folder in this repo instead of the archived standalone repo.

Motivation

• Keeps all examples co-located with the source code and documentation, making them easier to maintain and keep up to date.
• Reduces fragmentation across repositories.
• The examples/ folder can be extended in the future with additional setup examples (e.g., JavaScript flat config, path aliases, etc.).

Suggested Folder Structure

examples/
└── typescript/
    ├── package.json
    ├── tsconfig.json
    ├── eslint.config.js
    └── src/
        └── ...

Additional Context

The current epb-ts-example repo is already outdated. Archiving it and replacing the link in the TypeScript Support guide will ensure users always land on a maintained, working example.
