MAJOR ENHANCEMENT: Validation scripts now test OPERATIONS and document EVERYTHING

These scripts are now comprehensive discovery tools that:
1. Actually TEST operations (not just detect)
2. Document complete system knowledge for future reference

CRITICAL NEW TESTS:

Plesk validator (validate-plesk.sh):
  • NEW TEST 8: File ownership detection + cron user determination
    - Checks who owns document root files
    - Determines correct user for cron jobs
    - ANSWERS: Should we use www-data, owner, or domain-specific user?

  • ENHANCED TEST 9: Cron system operational testing
    - Actually WRITES test cron entry (then removes it)
    - Tests both standard crontab AND plesk bin cron
    - ANSWERS: Which cron system actually works?

  • NEW TEST 13: WordPress file permissions & wp-config.php access
    - Tests if we can read wp-config.php
    - Extracts database credentials
    - Determines database prefix pattern from REAL data

  • NEW TEST 14: Comprehensive system documentation
    - Catalogs ALL Plesk bin commands
    - Lists ALL domains on system
    - Documents ALL PHP versions
    - Records web server config (nginx + Apache detection)
    - Creates "QUICK REFERENCE FOR DEVELOPERS" section

InterWorx validator (validate-interworx.sh):
  • NEW TEST 11: WordPress file permissions & cron user testing
    - Extracts database name from wp-config.php
    - VERIFIES username_ database prefix from real data
    - Actually WRITES test cron entry (then removes it)
    - ANSWERS: Can we use crontab -u USER for cron jobs?

  • NEW TEST 12: Comprehensive system documentation
    - Catalogs ALL InterWorx bin commands
    - Lists ALL users on system
    - Lists ALL vhost configurations
    - Documents sample vhost config structure
    - Creates "QUICK REFERENCE FOR DEVELOPERS" section

WHAT THESE SCRIPTS NOW ANSWER:

Plesk - CRITICAL BLOCKERS:
  ✓ Who owns web files? (determines cron user)
  ✓ Can we write crontab entries?
  ✓ What's the database prefix pattern? (from real wp-config.php)
  ✓ Which cron system to use?
  ✓ All available Plesk commands
  ✓ Complete system inventory

InterWorx - VERIFICATION:
  ✓ Confirms username_ database prefix (from real data)
  ✓ Confirms crontab -u USER works
  ✓ Documents all InterWorx commands
  ✓ Complete system inventory

OUTPUT FORMAT:
Both scripts now generate comprehensive results files with:
  - Color-coded test results (PASS/FAIL/WARN)
  - Complete system documentation
  - Quick reference guide for developers
  - Actionable answers to critical questions

These scripts will learn EVERYTHING we need to know in one run!
