Ben c20b461e7d feat: Implement secure Trainer Announcements system with comprehensive features 
This commit introduces a complete announcement management system for HVAC trainers
with enterprise-grade security, performance optimization, and email notifications.

## Core Features
- Custom post type for trainer announcements with categories and tags
- Role-based permissions (master trainers can create/edit, all trainers can read)
- AJAX-powered admin interface with real-time updates
- Modal popup viewing for announcements on frontend
- Automated email notifications when announcements are published
- Google Drive integration for training resources

## Security Enhancements
- Fixed critical capability mapping bug preventing proper permission checks
- Added content disclosure protection for draft/private announcements
- Fixed XSS vulnerabilities with proper output escaping and sanitization
- Implemented permission checks on all AJAX endpoints
- Added rate limiting to prevent abuse (30 requests/minute)
- Email validation before sending notifications

## Performance Optimizations
- Implemented intelligent caching for user queries (5-minute TTL)
- Added cache versioning for announcement lists (2-minute TTL)
- Automatic cache invalidation on content changes
- Batch email processing to prevent timeouts (50 emails per batch)
- Retry mechanism for failed email sends (max 3 attempts)

## Technical Implementation
- Singleton pattern for all manager classes
- WordPress coding standards compliance
- Proper nonce verification on all AJAX requests
- Comprehensive error handling and logging
- Mobile-responsive UI with smooth animations
- WCAG accessibility compliance

## Components Added
- 6 PHP classes for modular architecture
- 2 page templates (master announcements, trainer resources)
- Admin and frontend JavaScript with jQuery integration
- Comprehensive CSS for both admin and frontend
- Email notification system with HTML templates
- Complete documentation and implementation plans

This system provides a secure, scalable foundation for trainer communications
while following WordPress best practices and maintaining high code quality.
