Eliminates one Anthropic API call entirely by using pattern matching:
- Add 120+ known single-company names (Ernst & Young, M&S, law firms, etc.)
- Detect "/" separator as clear indicator of multiple companies
- Use company suffixes (Ltd, PLC) to identify when "&" means two companies
- Conservative approach: don't split ambiguous cases
Added 40 unit tests for compound name detection covering:
- Known single companies with & and "and"
- Slash-separated company names
- Ambiguous cases
- Edge cases (empty, null, short names)
Estimated savings: ~$0.01 per CV check, 100% elimination of this API call
