Icogen — Windows icon & asset toolkit

Generate Windows app icons and WinUI 3 assets from a single source image, with zero runtime dependencies.

This release ships five standalone executables:

Binary	Purpose
`icogen-app.exe`	⭐ Recommended. Combined tool — a top tab bar switches between the Ico and Assets workflows over one shared source image.
`icogen-gui.exe`	AppIcon.ico only, with contain/cover mode, background color, padding and per-size preview.
`icogen-assets-gui.exe`	WinUI 3 / Windows App SDK asset PNGs only, with per-target toggles.

Binary	Purpose
`icogen.exe`	Generate AppIcon.ico with configurable sizes, scale mode and background.
`icogen-assets.exe`	Generate the eight WinUI 3 asset PNGs into `Assets\`.

# GUI (recommended)
icogen-app.exe

# CLI
icogen.exe logo.png
icogen-assets.exe logo.png

All binaries are self-contained — no .NET or other runtime required.

Added the combined icogen-app.exe with a top tab bar switching Ico / Assets over one shared source image.
Refreshed GUI design: drop zone, rounded primary button, SVG icons (upload / folder / theme), and a 2×4 target grid for the 8 assets.
Build scripts and docs updated for the five binaries.
