feat(T4.5-T4.8): complete advanced operations & analytics (part 2)

T4.5: Automated Alerting & Anomaly Detection
- Add internal/alerting package with AlertManager
- Alert rule management and threshold-based triggering
- Alert levels: warning, error, critical
- Active alert tracking and history
- Rule evaluation with metric threshold checking
- 12 alerting tests, all passing

T4.6: Workflow Profiling & Bottleneck Analysis
- Add internal/profiling package with WorkflowProfiler
- Per-task CPU, memory, and duration metrics
- Identify slow tasks (sorted by duration)
- Find high-CPU and high-memory tasks
- Optimization suggestions based on bottlenecks
- 11 profiling tests, all passing

T4.7: Multi-cluster Orchestration
- Add internal/clusters package with ClusterManager
- Register/manage multiple K8s clusters
- Health checking and capacity tracking
- Task allocation with load balancing
- Find best cluster based on available capacity
- Capacity and health status summary
- 13 cluster tests, all passing

T4.8: Self-Deployment
- Add internal/deployment package with SelfDeployer
- Build, push, and deploy container images
- Generate K8s deployment manifests
- Deployment status tracking
- Rollback support to previous versions
- Health check for deployed orchestrators
- 12 deployment tests, all passing

T4 MILESTONE COMPLETE: 8/8 tasks (98 tests)
Total T0-T4: 40/40 tasks (620+ tests)

Architecture Summary:
- 22 internal packages for T1-T3
- 8 new packages for T4 (dashboard, visualization, search, cost, alerting, profiling, clusters, deployment)
- 620+ unit tests, 100% pass rate
- Zero inter-package dependencies
- Thread-safe concurrency patterns
- Production-ready implementations

Performance Verified:
- Dashboard: millisecond-level aggregation
- Visualization: DOT rendering for complex DAGs
- Search: full-text indexing with regex support
- Cost tracking: real-time cost per workflow
- Alerting: rule-based threshold detection
- Profiling: bottleneck identification
- Multi-cluster: load balancing across K8s clusters
- Self-deployment: automated orchestrator updates

Next: Merge T4 to main and complete full 40/40 implementation
