feat: v0.1.8

[dantech2000]

[0.1.8] - 2025-08-05

Added

• Default Metrics Integration: Redesigned health checks to use AWS default metrics (EC2 CPU utilization) requiring no additional setup
• Kubernetes Client Integration: Implemented working kubeconfig integration for comprehensive workload validation
• Enhanced CloudWatch Integration: Added proper EC2 instance discovery via EKS and Auto Scaling APIs
• Graceful Degradation: Clear messaging when optional services (Container Insights, kubectl) aren't available
• Real-time Health Check Progress: Professional spinner-based UI with progress bars and status indicators
• Sample Health Check Output: Comprehensive health assessment display with color-coded status
• Health Check Documentation: Added detailed usage examples and prerequisite explanations

Fixed

• Removed Mock Data: Eliminated hardcoded fake metrics in health checks that could provide false confidence
• CloudWatch Metrics Fallback: Fixed issue where system returned fake utilization values when metrics unavailable
• Container Insights Detection: Added proper detection and setup guidance for Container Insights
• Memory Metrics Handling: Clear messaging that memory metrics require additional setup
• Output Duplication: Resolved issue where completion summary would duplicate progress display
• Kubernetes Client Implementation: Fixed placeholder function that always returned nil

Enhanced

• Health Check Categories: Clear distinction between blocking and warning-level checks
• Prerequisites Documentation: Detailed explanation of what works out-of-the-box vs requires setup
• Error Messages: User-friendly guidance with actionable steps for missing services
• CLI Short Flags: Added convenient short flags for all commands (-c, -n, -d, -f, etc.)
• AWS Error Handling: Improved error messages with specific guidance for credential and configuration issues

Technical Improvements

• EC2 Metrics Queries: Direct integration with AWS/EC2 namespace for CPU utilization
• Auto Scaling Integration: Added ASG client for comprehensive instance discovery
• Node Discovery Enhancement: Improved mapping between EKS nodegroups and EC2 instances
• Health Check Engine: Robust validation system with decision logic (PROCEED/WARN/BLOCK)
• Progress Monitoring: Clean ANSI escape code handling for seamless live updates
