chore: force CI re-run for PR #1039

Regression from audit #109: rows.Err() checks were removed from List,
ListGlobal, restartAllAffectedByGlobalKey, and Values between commits
3a30b073 and b25b4fb6. Without these checks, a mid-stream query error
(e.g. connection loss during iteration) is silently ignored and partial
results are returned as if the query succeeded.

Fix: add if err := rows.Err(); err != nil { log.Printf(...) } after
every for rows.Next() loop in secrets.go.
