Replace fuzzy string matching with semantic AI matching to fix false positives where similar-sounding but different companies were matched (e.g., "Families First CiC" incorrectly matching "FAMILIES AGAINST CONFORMITY LTD"). Changes: - Add ICompanyNameMatcherService interface and AICompanyNameMatcherService implementation using Claude Sonnet 4 for semantic company name comparison - Add SemanticMatchResult and related models for AI match results - Update CompanyVerifierService to use AI matching with fuzzy fallback - Add detection for public sector employers, charities, and self-employed entries that cannot be verified via Companies House - Update tests to work with new AI matcher integration Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
