Jira issue: CRDB-67401

Start by reproducing the reported SELECT st_asgeojson(_, _, _) failure, then read pkg/geo/encode.go around line 155 and the referenced go-geom GeometryCollection, Bounds, and GeoJSON encoding paths. Trace how the geometry reaches GeometryCollection.FlatCoords and define done as the query no longer panicking for the reported input.

Written by the indexing model from the issue text.
