Link traverse-framework/claude-skills from this README

[enricopiovesan]

Summary

traverse-framework/claude-skills is now the dedicated home for Claude Skills that help agents build apps with Traverse (starting with traverse-app-builder). This repo's README should link to it so people discover it the same way they discover registry and reference-apps.

Suggested fix

Add a short pointer in the README's "What Can I Build?" section or nearby, e.g.:

Building with an AI coding agent? See traverse-framework/claude-skills for verified Claude Skills that walk through authoring, composing, and validating capabilities.
