CS2 Video Config Editor v4.0.0

Version 4 replaces the PowerShell runtime with a self-contained C#/.NET 10 Windows application.

Highlights

One double-clickable x64 executable with no PowerShell or separate .NET runtime requirement.
Native WinForms interface with Steam account discovery, responsive display editing, live aspect preview, and backup restore.
Expanded catalog of 43 common display modes, from low-resolution 4:3 through high-resolution widescreen presets.
Fresh dark theme with teal-blue accents throughout controls, focus states, and the live preview.
Safe atomic configuration updates that preserve encoding, BOM state, and line endings.
Full compatibility with existing schema-1 preferences and timestamped editor backups.
New xUnit coverage and a .NET-based build, test, and release pipeline.

Console automation and privacy-safe diagnostic export are intentionally deferred from this GUI-first release.
