register_status_widget(): pure Python wrapper that adds a live widget to the main window status bar with context menu discoverability. Origin query bindings (kcsdk.list_origins, active_origin, get_origin, set_active_origin): thin C++ forwarding to OriginManager with Python wrappers using kcsdk-first routing. IOriginProvider and IStatusBarProvider C++ interfaces dropped — existing FileOrigin stack is already complete, and status bar widgets don't need C++ lifecycle management.

"""FileOrigin registration and query wrappers.
|
|
|
|
Wraps ``FreeCADGui.addOrigin()`` / ``removeOrigin()`` with validation
|
|
and error handling. Addons implement the FileOrigin duck-typed
|
|
interface directly (see Silo's ``SiloOrigin`` for the full contract).
|
|
|
|
Query functions (``list_origins``, ``active_origin``, etc.) route
|
|
through the ``kcsdk`` C++ module when available, falling back to
|
|
``FreeCADGui.*`` for backwards compatibility.
