The pull request enhances the organization merging feature by using a new library and a new field to compare organization names by edit distance. It modifies the backend/package.json, backend/src/database/repositories/organizationRepository.ts, and services/apps/search_sync_worker/src/repo/organization.repo.ts files to implement the new logic and synchronize the data between the databases.
