CRITICAL fixes:
- Stop passing mint URLs as relay URLs in initNDK (protocol mismatch)
- Add unit tests for buildTransactionHistory (dedup, fallback, sort)
HIGH fixes:
- Restore .claude entry in .gitignore
- Add warning logging for skipped malformed proof tags in nutzap parsing
- Add error handling + 30s timeout to NDK initialization
- Add unit tests for formatCSV and escapeField
- Export escapeField for testability
Also: add test script to package.json, include test/ in tsconfig
