.SYNOPSIS Main DevVm command dispatcher - provides a simplified CLI interface. .DESCRIPTION Provides a user-friendly command-line interface for DevVm operations. Similar to tools like nvm, sdkman, etc. .PARAMETER Command The subcommand to execute (use, current, list, install, available, activate, cache, system, help). .PARAMETER Runtime The runtime to operate on (node, java, maven, etc.). .PARAMETER Version The version to use or install. .PARAMETER Persist Where to persist the configuration (session, project, user, global). .PARAMETER All Show all available versions (not just latest of each release line). .PARAMETER Update Force fresh download of available versions, bypassing cache. .PARAMETER Verify Verify runtime commands after activation (show version output). .EXAMPLE devvm use node 18.9.1 devvm use java 11.0.2 -Persist project devvm current node devvm list node devvm install node 20.0.0 devvm available java devvm available java -All devvm available node -Update devvm system devvm cache devvm cache clean devvm activate devvm activate -Verify #> function Invoke-DevVm { [CmdletBinding()] param ( [Parameter(Position = 0)] [ValidateSet('use', 'current', 'list', 'install', 'available', 'activate', 'cache', 'system', 'help')] [string]$Command = 'help', [Parameter(Position = 1)] [string]$Runtime, [Parameter(Position = 2)] [string]$Version, [Parameter()] [ValidateSet('session', 'project', 'user', 'global')] [string]$Persist = 'session', [switch]$All, [switch]$Update, [switch]$Verify ) switch ($Command.ToLower()) { 'use' { if ([string]::IsNullOrWhiteSpace($Runtime)) { Write-Error "Runtime is required.
