Walks mcp-mirror/<device>/ trees, classifies each .st as PRG/FB/GVL/STRUCT/ENUM/METHOD/PROPERTY_GETTER/PROPERTY_SETTER/META/OTHER, counts non-blank LOC, and returns a Project tree. Property declarators (e.g. FB_Sweep/PropX.st alongside FB_Sweep/PropX/Get.st) are detected via a Get.st/Set.st child probe so they don't get classified as METHOD.
