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
