/**
 * LLM Data Storage Service
 *
 * Temporary storage solution for LLM (ChatGPT) data until full backend processing is implemented.
 *
 * Flow:
 * 1. When user connects ONLY LLM data → Store data locally, send metadata to backend
 * 2. When user accepts data request → Send stored LLM data directly to developer
 *
 * This is a TEMPORARY feature until full LLM data processing is available.
