/**
 * ai-functions - Full-featured AI primitives for building intelligent applications
 *
 * This package provides the complete feature set including:
 * - Core primitives from ai-core (generate, AIPromise, templates, context)
 * - Batch processing (BatchQueue, BatchMapPromise)
 * - Retry/resilience patterns (RetryPolicy, CircuitBreaker, FallbackChain)
 * - Budget tracking (BudgetTracker, TokenCounter)
 * - Caching (MemoryCache, EmbeddingCache, GenerationCache)
 * - Tool orchestration (AgenticLoop, ToolRouter)
 * - Embeddings
 * - Provider integrations
 *
 * For lightweight usage with just core primitives, use ai-core directly.
 *
 * @packageDocumentation
