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
