/**
 * GitMem Tier Detection and Feature Flags
 *
 * Three tiers:
 *   free — Local JSON storage, keyword search, zero config
 *   pro  — Supabase + embeddings, semantic search, cloud persistence, variants
 *   dev  — Everything in pro + compliance, transcripts, metrics
 *
 * Detection chain:
 *   1. GITMEM_TIER env var (explicit override — testing/dev)
 *   2. api_key in config.json or GITMEM_API_KEY env var:
 *      a. Check license-cache.json → if valid + not expired (72h) → return cached tier
 *      b. No cache → optimistic "pro" (validated async in runServer)
 *   3. No key + no SUPABASE_URL + no config.supabase_url → free
 *   4. No key + SUPABASE_URL set (env var) → pro (backward compat for us)
