.SYNOPSIS
    TwinCAT automation common functions.
    Sourced by all other scripts via . "$PSScriptRoot\tc-common.ps1"

.DESCRIPTION
    Provides:
    - Get-Dte          : create/attach TcXaeShell DTE COM object
    - Open-Solution    : open .sln and wait for System Manager
    - Get-SysManager   : extract ITcSysManager from the open project
    - Wait-Busy        : poll SolutionBuild.BuildState until idle
    - Write-Log        : timestamped console + file logging
