Advanced donor deduplication

Find duplicate donor records that exact-email matching misses — fuzzy name matching with Levenshtein distance, multi-signal rules combining phone, address, and name, and AND/OR conditional logic for sophisticated dedup queries. Built for the realities of imported data, married name changes, and donors who give from a personal email at home and a work email at the office. Catches duplicates before they pollute reports and split lifetime value across two records.
