The ad-hoc codesign path signed the whole bundle with one --deep pass,
which never carried --entitlements to the QuickLook appex, so PlugInKit
silently rejected it as unsandboxed. Sign nested code individually
instead, matching the Developer ID path.
Separately, ThumbnailProvider drew the extracted preview at its native
pixel size anchored at the CGContext origin (bottom-left) instead of
scaling it to fill request.maximumSize, producing a small thumbnail
stuck in one corner instead of a properly sized, centered icon.
Note: Gatekeeper still rejects an ad-hoc or unnotarized Developer-ID
signature outright, and PlugInKit periodically re-validates and drops
any registered plugin that fails that check — so these fixes are
necessary but not sufficient for thumbnails to render from a build
that isn't both signed and notarized.

With GPU analytical rendering handling circles, arcs, and ellipses,
tessellation geometry is now camera- and zoom-independent.
- Remove wpp from the tessellation memo guard hash to prevent clearing
all cached entities when zooming across quantization bands.
- Remove quantized_wpp from resident_wire_key and resident_wires_for
so all zoom levels reuse the cached resident set directly with zero
CPU re-tessellation.
- Fix clippy slice_from_raw_parts lint in dwg-thumbnailer without suppression.
- Update zoom test to assert Arc pointer equality across camera zooms.
Finder thumbnails and "Open with" registration fail in the field for
three compounding reasons: the app claims com.autodesk.dwg/.dxf but
never declares them (UTImportedTypeDeclarations was missing, so on
systems with no other declarer Launch Services can't bind the
extensions at all); the QuickLook appex only serves com.autodesk.dwg
while machines with AutoCAD installed resolve .dwg to its exported
com.autodesk.autocad.dwg (BricsCAD etc. likewise win with their own
UTIs); and the ad-hoc --deep signature carries no entitlements, but a
QuickLook thumbnail extension must be sandboxed
(com.apple.security.app-sandbox) before macOS will run it.
Import-declare both UTIs, claim and serve the AutoCAD variants too,
add the appex sandbox entitlements, and add
packaging/build_macos_signed.sh — a local mirror of the CI build-macos
job that signs with a Developer ID (hardened runtime, per-component
entitlements), notarizes and staples. DEVELOPER_ID=- reproduces the
CI ad-hoc build.

First real Windows build surfaced errors that a Linux host couldn't catch:
* Enable the missing `windows` feature gates (Win32_System_LibraryLoader,
Win32_System_SystemServices, Win32_Security — the last brings in the
`Ex` registry APIs) so the imports resolve.
* Depend on `windows-core`: the `#[implement]` macro expands to
`windows_core::` paths, which need the crate nameable in the root.
* `IClassFactory::LockServer` takes `Win32::Foundation::BOOL`, not a
`core` BOOL.
* Name the returned image type via a new `dwg_thumbnailer::RgbaImage`
re-export instead of a direct `image` dependency.
Verified with `cargo check --target x86_64-pc-windows-gnu -p
dwg-thumbnailer-win` (and the native check still passes).

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.
