Add comprehensive memory usage monitoring and cleanup triggers

[davedumto]

Problem

No monitoring of memory consumption across the application, leading to:

• Undetected memory leaks
• No alerts when memory usage is high
• No cleanup triggers for memory optimization
• Poor visibility into application performance

Impact

• Memory issues discovered only after problems occur
• No proactive memory management
• Potential server crashes from memory exhaustion
• Poor user experience during memory pressure

Solution

Implement comprehensive memory monitoring system:

• Real-time memory usage tracking
• Memory leak detection
• Automated cleanup triggers
• Memory usage alerts
• Performance metrics collection

Implementation

• Add memory monitoring middleware
• Implement memory usage thresholds and alerts
• Create automated cleanup processes
• Add memory metrics to monitoring dashboard
• Set up alerts for high memory usage

Acceptance Criteria

• Real-time memory usage monitoring
• Memory leak detection and alerts
• Automated cleanup triggers
• Memory usage dashboard/metrics
• Integration with existing monitoring system
• Alerts for memory thresholds (>80% usage)
