 * Exponential backoff with full jitter and a minimum delay floor.
 *
 * - Uses exponential growth capped at maxDelayMs
 * - Applies full jitter to spread retries uniformly across the window
 * - Enforces a minimum delay to avoid tight retry loops
 *
 * Example (baseDelayMs = 1000):
 *   Try 1:   250ms – 1,000ms
 *   Try 2:   250ms – 2,000ms
 *   Try 3:   250ms – 4,000ms
 *   Try 4:   250ms – 8,000ms
 *   Try 5+:  250ms – maxDelayMs
