blendertk v0.5.26

• 2026-07-25 — BREAKING: removed the flat wrappers btk.import_maya_scene, btk.bake_maya_scene, and btk.auto_instance — call the classes instead (mirrors mayatk). Migration: btk.import_maya_scene(p, **kw) → btk.MayaSceneImport().import_scene(p, **kw); btk.bake_maya_scene(p, **kw) → btk.MayaSceneImport().bake_scene(p, **kw); btk.auto_instance(objs, **cfg) → btk.AutoInstancer.run_once(objs, **cfg) (new @classmethod, config via **config). Internal callers (reference_manager) + tests migrated — the ui_handler reference-routing mocks now patch the instance methods (MayaSceneImport.import_scene/bake_scene) rather than the deleted module functions. Verified in fresh Blender 5.1: test_auto_instancer, test_scene_import, and test_blender_ui_handler (222/222), 0 failures.
