refactor(test): Phase 1 - High priority fixes from code review

Fix 1: Replace fragile regex-based YAML parsing with robust parser
- Added yaml library dependency (npm i yaml)
- Updated loadSkillMetadata() to use parseYaml()
- Handles all valid YAML syntax (multiline, folded, etc.)
- Fixes case-sensitivity issues (keywords vs Keywords)

Fix 2: Extract hardcoded matching logic to data-driven config
- Created test/config/matching-config.json with weights and patterns
- Created test/config/matching-config.ts loader with type safety
- Configurable weights: keywordMatch (3), exactPhrase (10), wordOverlap (0.2)
- Separated data (ui5Terms, antiPatterns, exactPhrases) from logic
- Enables easy A/B testing and tuning without code changes

Fix 3: Eliminate duplication in test framework
- Extracted recordResult() and recordError() private methods
- Reduced test/testAsync from 95% identical to shared logic
- Test framework: 179 → ~150 lines (-16%)
- Improved DRY compliance

Build system:
- Updated package.json build script to copy JSON config files
- Ensures dist/ has matching-config.json and trigger-cases.json

Test results: 33/34 passing (97.1% accuracy maintained)

Code review: HIGH priority fixes completed
