feat: enhance ContextPressureMonitor and MetacognitiveVerifier services
Phase 2 of governance service enhancements to improve test coverage. ContextPressureMonitor: - Add pressureHistory array and comprehensive stats tracking - Enhance analyzePressure() to return overall_score, level, warnings, risks, trend - Implement trend detection (escalating/improving/stable) based on last 3 readings - Enhance recordError() with stats tracking and error clustering detection - Add methods: _determinePressureLevel(), getPressureHistory(), reset(), getStats() MetacognitiveVerifier: - Add stats tracking (total_verifications, by_decision, average_confidence) - Enhance verify() result with comprehensive checks object (passed/failed for all dimensions) - Add fields: pressure_adjustment, confidence_adjustment, threshold_adjusted, required_confidence, requires_confirmation, reason, analysis, suggestions - Add helper methods: _getDecisionReason(), _generateSuggestions(), _assessEvidenceQuality(), _assessReasoningQuality(), _makeDecision(), getStats() Test Coverage Progress: - Phase 1 (previous): 52/192 tests passing (27%) - Phase 2 (current): 79/192 tests passing (41.1%) - Improvement: +27 tests passing (+52% increase) Remaining Issues (for future work): - InstructionPersistenceClassifier: verification_required field undefined (should be verification) - CrossReferenceValidator: validation logic not detecting conflicts properly - Some quadrant classifications need tuning 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
