Description

Documents the known Vitess streaming-result limitation behind #1193: Trickster must issue SHOW COUNT(*) WARNINGS on the same upstream connection to recover terminal status and warning metadata, and that hidden diagnostic can change FOUND_ROWS() for the client's next statement.

Closes #1193.
