- Remove card brands (VISA/MC/Amex) from _SKIP_LINE_RE so card-terminal
lines like "VISA USD$ 36.78" are no longer skipped
- Replace bottom-50% scan with full-text max scan (Pass 2): scans every
line in the receipt and returns the largest dollar amount, correctly
handling display-style receipts that show the charge at the top with
no label (e.g. LAYAL CAFE $40.10 before the item list)
- Update vendor LLM prompt to ask the model to correct OCR garbling
(e.g. "NeDonald's" → "McDonald's") and detect bank statements
- Add 4 new tests covering top-amount, card-terminal, max-beats-items,
and change-exclusion scenarios (71 tests, all passing)
