Support collider generation for Empties with Geometry Nodes geometry (Blender 5.2+)

[Weisl]

Summary

Since Blender 5.2, Empty objects can carry geometry produced by a Geometry Nodes modifier. Simple Collider currently can't generate colliders for these objects.

Current behavior

Object-type gating is centralized in VALID_OBJECT_TYPES (properties/constants.py), currently {'MESH', 'CURVE', 'SURFACE', 'FONT', 'META'}. EMPTY is not included, so empties are filtered out everywhere collider generation, validation, and conversion check object type (e.g. collider_shapes/add_bounding_primitive.py, validation/checks.py, collider_conversion/*).

Request

Allow generating bounding/mesh/remesh colliders from an Empty's evaluated Geometry Nodes output, similar to how modifier-evaluated mesh data is already pulled from regular mesh objects (use_modifiers path in add_bounding_primitive.py).

Notes / open questions

• Needs the evaluated geometry pulled via depsgraph (object.evaluated_get(deg) + bpy.data.meshes.new_from_object(...)) since an Empty has no .data mesh/curve of its own.
• Should confirm behavior when the Geometry Nodes tree outputs non-mesh geometry (curves, points, instances) - likely out of scope initially, mesh output only.
• Touches the same VALID_OBJECT_TYPES gate used across validation and naming/conversion, so adding EMPTY needs to be checked against each of those call sites, not just the primary generation path.
