feat(iace): add hazard-matching-engine with component library, tag system, and pattern engine

Implements Phases 1-4 of the IACE Hazard-Matching-Engine:
- 120 machine components (C001-C120) in 11 categories
- 20 energy sources (EN01-EN20)
- ~85 tag taxonomy across 5 domains
- 44 hazard patterns with AND/NOT matching logic
- Pattern engine with tag resolution and confidence scoring
- 8 new API endpoints (component-library, energy-sources, tags, patterns, match/apply)
- Completeness gate G09 for pattern matching
- 320 tests passing (36 new)
