C3D-0348 · READ-ONLY: probe the PointGroup API surface before building the stake-out recipe [C3D-APIPROBE] error

Reflects over PointGroup and the PointGroups collection to list every property and method available on this Civil 3D build (QueryBuilder does not exist here, so membership must be set another way). Also dumps the current group order, checks that the intended point and label styles exist by exact name, and tests whether E:\DATA is reachable from the plugin. Writes nothing.
