feat: add red-green 3D mode and Windows Forms GUI

- add rg (red-green) anaglyph subtitle mode with configurable horizontal offset
- extend CLI mode handling to support sbs, ou, and rg
- add offsetx option for anaglyph subtitle positioning
- add Windows Forms GUI project for configuring and running conversions
- add file pickers for input/output paths in the GUI
- add GUI controls for mode, resolution, font size, and offset
- add status output and mode-aware UI behavior in the GUI
- update mode selection handling to support user-friendly display labels
