feat(T4.1-T4.4): implement advanced operations & analytics (part 1)

T4.1: Real-time Metrics Dashboard - Add internal/dashboard package with MetricsAggregator - Record, aggregate, and query metrics - Percentile calculations (p50, p95, p99) - Time-series data with max size eviction - 13 metrics tests, all passing T4.2: Workflow Visualization & DAG Rendering - Add internal/visualization package with DAGRenderer - Convert dependency graphs to DOT format - Critical path highlighting - Topological sorting with parallel task detection - HTML rendering for visualization - 11 DAG rendering tests, all passing T4.3: Advanced Search & Filtering - Add internal/search package with WorkflowSearch - Full-text indexing with word-based lookup - Filter by status, assignee, tag, date range - Regex pattern matching - Saved filters for reusable queries - 15 search tests, all passing T4.4: Cost Tracking & Optimization - Add internal/cost package with CostTracker - Track LLM API costs (by token) - Track git operation costs - Track compute resource costs (by duration) - Cost aggregation by workflow/type - Optimization recommendations - 11 cost tests, all passing Total T4.1-T4.4: 50 tests passing Next: T4.5-T4.8 (alerting, profiling, multi-cluster, self-deployment)
