a7d85fe148On the first launch that hasn't answered it yet, the app shows a small
dialog offering to become the default handler for .dwg and .dxf files.
The choice is persisted (default_assoc_prompted) so the prompt never
reappears.
The platform plumbing lives in io/file_association.rs:
* Windows — opens the OS's own per-app default-programs dialog via
IApplicationAssociationRegistrationUI::LaunchAdvancedAssociationUI,
passing the "Open CAD Studio" RegisteredApplications name the MSI
registers. Modern Windows guards the actual default behind a
UserChoice hash, so this is the supported consent path.
* Linux — xdg-mime default against the installed .desktop file, whose
MimeType entries already cover image/vnd.dwg and image/vnd.dxf.
* macOS — LSSetDefaultRoleHandlerForContentType binds the DWG/DXF UTIs
declared in Info.plist to the app bundle id.
The work runs on a dedicated thread (the Windows dialog is modal) with
the result delivered back through a oneshot channel and surfaced in the
command line.
