feat(thumbnails): embed DWG previews and wire cross-platform file thumbnails Round-trip a raster preview through the DWG's embedded preview slot and surface it to the OS file managers, so drawings show their contents in Explorer / Finder / Nautilus instead of a generic document icon. OCS: * io::thumbnail — rasterize the scene to a BMP DIB on save (embedded via acadrust's new Preview type) and read it back on open for the Start page recent list; `--dwg-thumbnail IN OUT SIZE` CLI extracts a badged PNG for external thumbnailers. * io::file_association::install_thumbnailer — self-install the OS integration on startup: Linux writes a .thumbnailer + hicolor mimetype icons; Windows registers the IThumbnailProvider DLL under HKCU. Shared core: * crates/dwg-thumbnailer — lean (image-only) preview extractor + the `badge_dwg` full-width "DWG" band, used by every platform so the ribbon is single-sourced. Ships an rlib+staticlib. * crates/dwg-thumbnailer-win — IThumbnailProvider COM in-proc server (cfg(windows), CI-built as a workspace member). * macos/ — QuickLook thumbnail extension (Swift + C-ABI bridge to the core staticlib), assembled into a .appex. Icons & packaging (single SVG source -> per-platform assets in CI): * assets/mimetypes/image-vnd.{dwg,dxf}.svg — themed file icons. * packaging: WiX ships dwg/dxf.ico + the thumbnail DLL and points the ProgIds at them; Info.plist gets CFBundleTypeIconFile + the QuickLook extension in Contents/PlugIns. * release.yml — generate .ico (Windows) and .icns (macOS) from the SVGs, build the QuickLook .appex, and bundle everything.

# Shared extraction core. Consumers: OpenCADStudio (Linux, via its own
# `--dwg-thumbnail` mode), the Windows `IThumbnailProvider` DLL, and the macOS
# QuickLook extension.
# rlib — OCS and the Windows DLL call `extract` directly.
# staticlib — the macOS QuickLook extension links the C ABI (`dwg_thumbnail_png`).
