v1.2.1 Machine-Readability and Discoverability Update (Research Hub Metadata Refresh)

This release improves machine readability, search discoverability, and crawler accessibility across the research hub website.
The goal is to make the site easier to index, parse, cite, and navigate for GitHub, search engines, AI crawlers, and scholarly tooling.

• Added CITATION.cff with structured citation metadata
• Added explicit URL pathways in CITATION.cff for both the top page and works.html
• Added LICENCE under CC BY 4.0 (Creative Commons Attribution 4.0 International)
• Reworked README.md to clearly position the repository as an academic/scientific research hub
• Enhanced index.html with SEO/crawler metadata (canonical, robots, Open Graph, Twitter cards, etc.)
• Expanded JSON-LD in index.html to strengthen structured links to works.html, RSS, and CITATION.cff
• Refined Core Research Areas in index.html to align with publication themes (including first-principles formalization of intelligence)
• Enhanced works.html with SEO metadata, canonical URL, and direct links to RSS/sitemap/CITATION endpoints
• Upgraded CollectionPage JSON-LD in works.html with stronger page-level context and stable entity references
• Added a machine-readable endpoints guide near the top of works.html

These changes improve the site’s reliability as a discoverable, machine-readable academic research hub.
