docs: fill the traversal row in the 0.1.0 check-record table

The check was already verified and marked done in TODO; the record table row was
still blank. Fills it from the existing evidence (Blender pre-check + in-engine
swept transect, 0 holes, ground Z 317..395).

All six 0.1.0 release checks now read PASS in the table.
