port 2V2-d.2: Granny runtime on libgr2, main character model animates
Implement the Granny SDK 2.11 API the client uses on top of libgr2 (platform/EterGrnLib/GrannyRuntime.cpp, shim granny.h declared from the SDK header): file sections, type-definition vertex conversion, material textures by Usage, mesh/bone bindings, deformer, control clock/loop/ease and weighted SRT sampling. Port EterGrnLib (LODController, Material, Mesh, Model, ModelInstance*, Motion, Thing, ThingInstance, Util) plus EterLib GrpObjectInstance/GrpCollisionObject/CollisionData verbatim and drop their platform skeletons and pending stand-ins; register the gr2 resource factory; vertex/index buffers are CPU-side until the 2V2-e render adapter. app.UpdateGame/RenderGame now run 40250's bodies, reaching the CPythonApplication members through their singletons (the platform has no app object); CPythonGraphic joins GameSingletons in member order, and GetMousePosition reads the host cursor. port.login_flow asserts the main instance's PART_MAIN model has meshes, its diffuse image loaded and the WAIT motion moves the bones between frames; offline and live pass, port_gate macos PASS.
