.SYNOPSIS
    Generate diff between two CODESYS text exports

.DESCRIPTION
    Compares two directories of exported CODESYS text files (.st) and generates
    unified diffs showing additions, modifications, and removals.

.PARAMETER BaseDir
    Directory containing the base/original export (before changes)

.PARAMETER TargetDir
    Directory containing the target export (after changes)

.PARAMETER OutputDir
    Directory to write diff files to

.EXAMPLE
    .\codesys-diff.ps1 -BaseDir ".\export_v1" -TargetDir ".\export_v2" -OutputDir ".\diffs"
