 * Gospel Message Tester — Full Chain Validation

 * Validates every step:
 *   1. API call → raw response
 *   2. Gospel reference parsing
 *   3. Archive matching + scoring
 *   4. Final message
 *
 * Usage:
 *   node test.js today
 *   node test.js 2026-04-17
 *   node test.js 2026-04-17 2026-04-02 2026-03-07   ← multiple dates at once
