/**
 * Worker Dispatch Service
 *
 * Implements the 12 background worker triggers from agentic-flow@alpha:
 * - ultralearn: Deep knowledge acquisition
 * - optimize: Performance optimization
 * - consolidate: Memory consolidation
 * - predict: Predictive preloading
 * - audit: Security analysis
 * - map: Codebase mapping
 * - preload: Resource preloading
 * - deepdive: Deep code analysis
 * - document: Auto-documentation
 * - refactor: Refactoring suggestions
 * - benchmark: Performance benchmarks
 * - testgaps: Test coverage analysis
 *
 * Performance Targets:
 * - Trigger Detection: <5ms
 * - Worker Spawn: <50ms
 * - Max Concurrent: 10 workers (configurable)
