/**
 * Aggressive pruning strategy - automatically prunes tool calls based on
 * token thresholds and tool value.
 *
 * Two-tier approach:
 * 1. At warnThreshold: prune error/low-value tools first
 * 2. At criticalThreshold: prune oldest tools regardless of type
 *
 * Both tiers target warnThreshold as the goal, providing a 40k buffer.
 * Sets aggressivePruneExhausted flag if still above criticalThreshold after pruning.
