Installed builds already register a handler (MSI ProgIDs, the Linux
.desktop MimeType, the macOS Info.plist), but the portable .exe and the
AppImage register nothing, so they never appear in the OS "Open with"
list. Add a best-effort, idempotent runtime registration that runs
silently on a detached thread at startup:
* Windows — writes HKCU\Software\Classes\Applications\OpenCADStudio.exe
(open command + FriendlyAppName + SupportedTypes .dwg/.dxf), which is
what lists the exe in "Open with → Choose another app".
* Linux — writes a user-level .desktop pointing at the running binary
($APPIMAGE when set) and refreshes the desktop database. Skipped when
a system package already provides the desktop entry, so we never
shadow a distro install.
* macOS — no-op; .app bundles auto-register with LaunchServices.
Unlike the default-app prompt this changes no defaults and shows no UI;
it only makes the binary discoverable as a handler.
