Add Bonanza Produce multi-invoice statement template

- Added multi-invoice template for Bonanza Produce with :multi and :multi-match? flags
- Template uses keywords for statement header to identify multi-invoice format
- Extracts invoice-number, date, customer-identifier (from RETURN line), and total
- Parses 4 invoices from statement PDF 13595522.pdf
- All tests pass (29 assertions, 0 failures, 0 errors)

- Added test: parse-bonanza-produce-statement-13595522
- Updated invoice-template-creator skill: emphasized test-first approach
