Add Codex marketplace metadata and a repo-local plugin scaffold so the repository can be installed as a Codex plugin without duplicating the skills catalog.
Document the new integration path and cover it with a regression test to keep the marketplace entry and plugin manifest in sync.
Add visible FAQ and concepts content, strengthen tool-specific integration
guides, and publish a dedicated skills-vs-MCP explainer.
Extend homepage SEO metadata and JSON-LD so the GitHub Pages catalog
better reflects the repository's real positioning and common user
questions.
