✨ feat(BIP): add weighted parameter error analysis algorithm

Implement intelligent BOM error analysis module that:
- Extracts and analyzes failed order matching attempts
- Uses feature-weight algorithm (azxs=10000, bkxs=1000, etc.) for accurate parameter conflict detection
- Automatically traces unmatched parameters to root cause
- Splits multi-error results into separate rows for detailed analysis
- Exposes BomExtractor data pool via GetAllItems() for external analysis

This solves fuzzy tie problems that caused parameter false positives in previous matching logic.
