Implement advanced variant/SKU system with new Trek XML fields

- Add rootProductStockCode, isOptionOfAProduct, isOptionedProduct to Trek XML parsing
- Expand product tuple structure (12 fields: +root_stock, +is_option, +is_optioned)
- Implement proper XML parsing for SKU lookup (vs regex patterns)
- Add 3-level SKU matching: variants → main products → root lookup
- Fix field names: price→priceTaxWithCur, producturl→productLink
- Add fallback regex method for XML parsing errors
- Successfully tested: 501 variants, 226 products with variants

Enables precise warehouse ProductCode to Trek XML stockCode matching
and better variant/main product relationship handling.
