refactor: migrate to kindred-addon-sdk for overlay, origin, and theme (#250)

Replace FreeCADGui.registerEditingOverlay() with kindred_sdk.register_overlay().
Replace FreeCADGui.addOrigin()/removeOrigin() with kindred_sdk wrappers.
Replace hardcoded _MOCHA dict with kindred_sdk.get_theme_tokens().
Add sdk dependency to package.xml <kindred> element.
