Add Loadwatch Health Analyzer for system monitoring analysis

NEW FEATURE: Loadwatch Health Analyzer
- Comprehensive system health analysis from loadwatch monitoring logs
- Time-range analysis: 1h, 6h, 24h, 7d, 30d options
- Intelligent problem detection and trending

CAPABILITIES:
- Memory pressure detection (low available memory, high swap usage)
- CPU saturation analysis (idle %, iowait, steal time)
- Load average trending and threshold detection
- Process issue detection (zombie processes, high CPU/MEM consumers)
- MySQL performance monitoring (slow queries, thread counts)
- Network connection analysis
- Historical trending across snapshots (3-minute intervals)

IMPLEMENTATION:
- modules/diagnostics/loadwatch-analyzer.sh - Main analyzer script
- Handles symlinked loadwatch directories
- Parses 7 log sections: alerts, summary, memory, CPU, tasks, MySQL, network
- Generates detailed reports with actionable recommendations
- Saves reports to tmp/ directory for review

INTEGRATION:
- Added to Performance & Diagnostics menu (option 10)
- Time range selection submenu for user-friendly access
- Updated README.md with feature documentation and usage examples

ANALYSIS FEATURES:
- Swap threshold alerts (>= 50% usage)
- CPU saturation detection (< 10% idle)
- High I/O wait warnings (> 20%)
- Zombie process tracking
- Memory availability trending (avg/min/max)
- Top CPU consumers aggregated across period

Perfect for:
- Post-incident investigation
- Capacity planning
- Performance trending
- System health monitoring
- Identifying resource bottlenecks

Works with servers that have loadwatch monitoring enabled
(logs in /root/loadwatch or /var/log/loadwatch)
