// Universal AI Agent - zero-dependency Node server (Node 18+)
// Features:
// - POST /chat { message, role?, optimizePrompt?: boolean }
// - Lightweight prompt optimizer (heuristics)
// - File-backed memory (memory.json)
// - Optional LLM call via OPENAI_API_KEY or ANTHROPIC_API_KEY using global fetch
// - CORS for local use
