BATCH-FIRST: Use prefab_instantiate_batch when spawning 2+ prefab instances.

Guardrails

Mode: Full-Auto required

DO NOT (common hallucinations):

• prefab_create_from_object does not exist → use prefab_create (takes scene object name/instanceId and savePath)
• prefab_spawn does not exist → use prefab_instantiate
• prefab_edit / prefab_modify do not exist → use prefab_set_property (edit prefab asset directly) or instantiate, modify, then prefab_apply
• prefab_save does not exist → use prefab_apply (applies instance changes to source prefab)

Routing:

• To modify components on a prefab instance in scene → use component module skills, then prefab_apply
• To set a property directly on the prefab asset → prefab_set_property (this module)
• To find all instances of a prefab → prefab_find_instances (this module)
