Keep the export probe, and the uid files beside the new scripts

_export_probe.gd is the check that found the empty planets: run inside a
built pack with --main-pack, it reports how many planet setups the registry
actually finds and what garrisons they carry. The suite runs from source and
structurally cannot see an export-only fault, so this is the thing to run
before a deploy.

The .uid files go with it because the repo tracks one beside every other
script; the ones added this session were left behind.
