Shared Intelligence Singletons (intelligence/shared-instances.ts)

Provides process-wide CacheEngine, TokenCounter, and MetricsCollector singletons for intelligence tools. Reuse it so new tools share one cache, one token count, and one metrics stream.

/**
 * Shared Singleton Instances for Intelligence Tools
 *
 * This module provides true singleton instances of CacheEngine, TokenCounter,
 * and MetricsCollector that are shared across ALL intelligence tools.
 *
 * This ensures:
 * - Consistent cache state across all tools
 * - Unified metrics collection
 * - Accurate token counting across the system
 * - Memory efficiency (single instances instead of per-tool instances)
