Changes in v2.0.0 Refactor

🎉 Summary

Complete overhaul of the Salesforce Setup Navigator extension from a broken monolithic codebase to a professional, modular, tested, and secure extension.

🔴 Critical Fixes

1. Fixed Broken Manifest (EXTENSION DIDN'T WORK!)

  • Issue: Domain pattern was *.my.salesforce-setup.com (doesn't exist)
  • Fix: Updated to proper Salesforce domains
  • Impact: Extension now actually works on Salesforce

2. Refactored Monolithic File

  • Before: 819 lines in content.js
  • After: 148 lines orchestrator + 6 focused modules
  • Impact: Maintainable and understandable code

3. Fixed config.js

  • Before: Raw JSON array
  • After: Proper JavaScript with const DEFAULT_MENU_CONFIG
  • Impact: No more ReferenceError
