Jira issue: CRDB-65769

Start by reproducing the reported SELECT crdb_internal.force_panic(_) query and trace the execution through pkg/sql/sem/builtins/builtins.go, pkg/sql/colexecerror/error.go, and pkg/sql/conn_executor.go. Compare the intentional panic path with the surrounding vectorized execution and error-catching behavior; completion is undefined until the expected behavior for this report is established.
