Summary
Enhance transaction deduplication to use configurable fuzzy matching, reducing duplicate transactions during imports and syncs.
Root Cause
Current deduplication logic relied on exact field matching, which missed duplicates with minor variations (e.g., typos, amount rounding).
Fix
deduplicateTransactionsutility using string similarity with configurable threshold and fields.docs/deduplication.md.Test Plan
npm test tests/utils/deduplication.test.ts– all should pass.DEDUPLICATION_THRESHOLDand confirm that borderline cases are handled accordingly.
