Add researcher identity merge guard

[telemarkdigital-publisher]

/claim #15

Summary

Adds researcher-identity-merge-guard, a focused Community & User Reputation System slice for safe researcher profile consolidation before reputation, CRediT-style contribution credit, badges, leaderboards, or private review history can transfer between merged profiles.

The guard evaluates synthetic merge packets for:

• independent verified identity proofs across ORCID, GitHub, and institutional email evidence
• ORCID and GitHub alias conflicts
• stale institutional email evidence
• projected reputation or credit spikes after merge
• open source-profile objection windows
• anonymous, double-blind, or private review history exposure
• missing institutional steward approval
• duplicate publication or contribution-credit collisions
• missing durable audit receipts

Demo Video

Required short demo video is included at:

researcher-identity-merge-guard/reports/demo.mp4

It is a generated synthetic slate only. It does not capture a desktop, browser, credentials, personal files, API keys, or private researcher data.
