Joseph HENRY 8ef75df9eb Fix mypy compatibility and add 5.0 conformance tests
- Qualify bare "object" as builtins.object in bpy.types to avoid shadowing
  by Context.object and similar properties
- Use _Sequence alias import to fix mypy "collections.abc.Sequence not defined"
- Filter out variables that clash with submodule re-exports (e.g. bpy.app)
- Add 5.0 conformance tests from Blender 5.0 mathutils documentation
