/**
 * Event Triage — classifies coordinator events as "routine" or "creative"

 *
 * Tier 1 (auto-response rules at PTY worker) already handled before we get here.
 * This module splits the remaining events into:
 * - "routine": simple approvals, permissions, config prompts → small LLM (~1-2s)
 * - "creative": error recovery, design questions, task evaluation → Milaidy (~5-10s)
 *
 * Pure functions — no side effects, same pattern as stall-classifier.ts.
