feat: Reduce false positives in company verification

Major improvements to company name matching accuracy:

- Add well-known brands dictionary with correct Companies House numbers
  for fast-track verification (Boots, Legal & General, EY, etc.)
- Add safe expansion words (UK, LIMITED, GROUP, PLC) that don't change
  company identity
- Fix core word validation to require original company's core words
- Remove overly aggressive skip words that removed meaningful identifiers
  (industries, technology, consulting, services, etc.)
- Add industry context hints for AI matching
- Fix CVBatchTester JSON deserialization for test files

Before: 98% verified but with false positives like:
- Boots → BOOTS AND BEARDS (wrong)
- Legal & General → LEGAL LIMITED (wrong)

After: 97% verified with correct matches:
- Boots → BOOTS UK LIMITED (correct)
- Legal & General → fast-tracked to correct company

-           - "Yorkshire Electricity" → "YORKSHIRE ELECTRICITY GROUP PLC" ✓ (same utility)

-           - "Families First" ≠ "FAMILIES AGAINST CONFORMITY" (different words after "Families")

-           - "Royal Bank" ≠ "Royal Academy" (Bank ≠ Academy)
+           - "Legal & General" ≠ "LEGAL LIMITED" ✗ (major insurer is NOT a generic "legal" company)
-           - "Storm Ideas" ≠ "STORM LIMITED" (missing "Ideas" - could be different company)
+           - "Checkout.com" ≠ "XN CHECKOUT LIMITED" ✗ (fintech is NOT an unrelated checkout company)
+           - "EY UK" ≠ "EY UK GDPR REPRESENTATIVE LIMITED" ✗ (main employer, not a subsidiary)
 
-        3. Legal suffixes (Ltd, Limited, PLC, LLP, CiC) should be ignored when comparing names
+        3. KEY DISTINCTION - Geographic/legal suffixes are OK, but new business words are NOT:

+           - "Paramount Consulting UK" → "PARAMOUNT LIMITED" ✗ (missing "Consulting" - different type)
+           - "Apex Technology Partners" → "APEX LIMITED" ✗ (missing "Technology Partners")
 
-        4. Adding "THE" or "GROUP" to a name doesn't make it a different company
+        4. Legal suffixes (Ltd, Limited, PLC, LLP, CiC) should be ignored when comparing names
 
-        5. If unsure, prefer matching over rejecting when core identifying words match
+        5. Adding "THE", "GROUP", "UK", or "HOLDINGS" to a name doesn't make it a different company
+
+        6. When the CV mentions a well-known brand, prefer the main operating/holding company over obscure matches
+
+        7. If INDUSTRY CONTEXT is provided, use it to reject candidates clearly in different industries
 
         CRITICAL: Return the COMPLETE company number exactly as shown (e.g., "SC083026", "02366995").
         Do NOT truncate or abbreviate the company number.
