Why

How

🤖 Generated by Copilot at 0503354

• Order the results of getMembersToMerge by similarity score instead of joined date (link). This improves the user experience by showing the most similar members first in the merge interface. The similarity score is calculated using a combination of factors such as name, email, location, and skills in the backend/src/database/repositories/memberRepository.ts file.
