feat: integrate memory system with UOK kernel (Phase 1)

- Add recordUnitOutcomeInMemory() to unit-runtime.js
- Records successful/failed unit completions as learned patterns
- Stores completion outcomes with appropriate confidence scores
  * 0.9 for successful completions
  * 0.5 for failures (lower confidence)
- Gracefully degrades when DB unavailable (never blocks UOK)
- Handles all unit status types (completed, failed, blocked, stale)

Memory Integration Benefits:
- UOK now learns from every unit execution
- Dispatch decisions can use learned patterns (Phase 2)
- Foundation for autonomous pattern recognition
- Zero performance impact (fire-and-forget async)

Tests Added:
- 18 comprehensive test cases covering:
  * Success/failure recording
  * Confidence score assignment
  * Graceful degradation
  * Pattern quality and description
  * Error handling
  * Database unavailability
  * Integration with UOK lifecycle

This enables Phase 2 (dispatch-based ranking) and Phase 3 (gate context).
