Cross-platform prerequisite for OS-level file associations: the boot task now consumes `std::env::args_os().nth(1)` as a path and dispatches `Message::OpenRecent` for it. Flag-style args (starting with `-`) are ignored, and `OpenRecent` already does the file-existence check, so a bogus path lands as a clean command-line error instead of a panic. Linux: the AppImage's desktop entry adds `image/vnd.dwg` alongside the existing `image/vnd.dxf` MIME type and grows a `%f` placeholder in `Exec=` so the launcher forwards the picked file path. Once the AppImage is integrated with the system (xdg-mime / AppImageLauncher), double-clicking a .dwg / .dxf opens it in Open CAD Studio. Windows: new `packaging/windows/main.wxs` defines an MSI installer — per-machine install to `Program Files\Open CAD Studio`, Start Menu shortcut, `MajorUpgrade` so newer MSIs replace older ones, and a single ProgID `OpenCADStudio.Drawing` that owns both `.dwg` and `.dxf` and launches the exe with the file as `argv[1]`. The icon is pulled from the SVG logo, converted to multi-resolution ICO at build time with the runner's pre-installed ImageMagick. CI now also runs `candle` / `light` (WiX Toolset 3, pre-installed on `windows-latest`) and uploads both the bare `.exe` (portable) and `.msi` (installer) to the release. macOS Info.plist already declares the DWG / DXF UTIs; combined with the argv-handling change above, double-clicking a drawing in Finder will open it in Open CAD Studio without further packaging changes.
