⏰ Tweet Schedule Optimizer

/**
 * ============================================================
 * ⏱️ Tweet Schedule Optimizer — Production Grade
 * ============================================================
 *
 * @name        tweetScheduleOptimizer.js
 * @description Analyzes your historical tweet performance by
 *              time of day and day of week, then generates a
 *              personalized optimal posting schedule. Uses
 *              weighted scoring across engagement rate, reply
 *              ratio, and retweet ratio to surface the best
 *              time slots for maximum reach.
 * @author      nichxbt (https://x.com/nichxbt)
 * @version     1.0.0
 * @date        2026-02-24
 * @repository  https://github.com/nirholas/XActions
 *
 * ============================================================
 * 📋 USAGE:
 *
 * 1. Go to your profile (x.com/YOUR_USERNAME)
 * 2. Open DevTools Console (F12)
 * 3. Paste and run — auto-scrolls and collects data
 * 4. Outputs your personalized optimal schedule
