Add knowledge graph author affiliation disambiguation

[absalonCRC]

/claim #17

Summary

Adds knowledge-graph-author-affiliation-disambiguation, a self-contained trust layer for Scientific Knowledge Graph Integration.

This slice focuses on author and affiliation entity quality before the graph is used for entity pages, lab-to-lab collaboration maps, semantic navigation, or AI recommendations.

What changed

• Deterministic author-name, affiliation, ORCID, email-domain, DOI, and concept normalization
• Evidence scoring for author mention merges
• Safe homonym handling via a curator queue instead of unsafe graph merges
• Collaboration edge generation from shared document evidence
• Recommendation suppression guards for uncertain author identities
• schema.org-compatible creator metadata export
• Synthetic sample mentions, tests, requirement map, CLI demo, SVG, and short MP4 demo

Distinctness

This avoids duplicating broad knowledge graph extractors, navigators, link-audit modules, ontology-drift migration controls, conflict arbiters, or knowledge-gap explorers already submitted. It targets the issue requirement for authors, affiliations, entity pages, collaboration maps, and reliable recommendations.
