/**
 * predict_yield Tool
 *
 * ML-based yield forecasting for vault APR prediction.
 * Analyzes historical performance to predict future returns.
 *
 * Use cases:
 * - Investment planning and return projections
 * - Yield farming strategy optimization
 * - Risk-adjusted return forecasting
 * - Performance trend analysis
 * - Performance: ~400-600 tokens per prediction
 *
 * Cache strategy:
 * - 60-minute TTL (predictions valid for moderate duration)
 * - Cache key: yield_prediction:{chainId}:{vaultAddress}:{timeRange}
 * - Cache hit rate target: 75-85%
 * - Cache tags: [CacheTag.VAULT, CacheTag.APR, CacheTag.ANALYTICS] for invalidation
