/**
 * Fragment Evolution Engine
 *
 * The core of prose: evolve semantic fragments as new messages
 * are processed. Each fragment sees its own previous state and produces
 * an updated version - evolution, not extraction.
 *
 * Uses a cheap LLM (Gemini 3 Flash via OpenRouter) for fast, affordable
 * compression of conversation into structured memory.
