[scottbrown]

Problem

No automated way to verify that dotfiles are properly installed and working correctly across different systems.

Solution

Create a comprehensive health check system:

• health-check.sh - Verify all package installations and configurations
• System compatibility checks
• Configuration validation
• Status reporting for all managed tools

Benefits

• Automated verification of dotfiles installation
• Quick diagnosis of configuration issues
• Confidence in system setup
• Easier troubleshooting and debugging

Implementation Notes

• Check for existence and proper linking of all configuration files
• Validate tool installations and versions
• Test key functionality of configured tools
• Provide detailed status reports with actionable feedback
• Support both quick checks and comprehensive validation modes
