    <#
    .SYNOPSIS
    CLAConfig is a class that provides validation to CLA YAML/JSON configuration files
 
    .DESCRIPTION
    CLAConfig implements a singleton configuration management class that manages configuration state throughout the PowerShell session. It integrates tightly with
    CLAConfigValidator to provide validation using JSON Schema and default rules.
 
    .EXAMPLE
    # Basic usage - Get singleton instance and load configuration
    using module '.\CLAConfig.psm1'
    $Config = [CLAConfig]::GetInstance()
    $Success = $Config.LoadConfig("C:\MyConfig\cyber-config.yaml")
 
    .EXAMPLE
    # Access default values and configuration schema

    $AllProducts = [CLAConfig]::CLADefault('AllProductNames')
    $SupportedEnvironments = [CLAConfig]::GetSupportedEnvironments()
