Included AI skills

This project includes four AI skills focused on managing a llms.txt file:

• validating: check whether a given llms.txt file (local path or URL) is valid and guide fixes until it passes (llms-txt-validate.md).
• initialising: create an initial llms.txt file (defaults to llms.txt in the repo root) and verify it with validation (llms-txt-init.md).
• info: summarise metadata (sections, links, last modification, file details) and suggest next steps (llms-txt-info.md).
• checking links: run link checking for URLs in llms.txt and help fix broken or redirected links (llms-txt-check-links.md).
