- Bump SDK_VERSION to 1.0.0 in version.py and package.xml
- Remove <pure_python> tag from package.xml (kcsdk is C++)
- Remove all FreeCADGui.* fallback paths in context.py, dock.py,
toolbar.py, menu.py; require kcsdk module
- Remove query fallbacks in origin.py (keep register/unregister
which still need FreeCADGui.addOrigin/removeOrigin)
- Add deprecation warnings to 11 superseded FreeCADGui methods
in ApplicationPy.cpp (not addOrigin/removeOrigin)
- All 39 Tier 1 tests pass
