### Task Summary Part of #5363. To show a finished execution's results without a computing unit, a reader has to know, for each operator, whether its result is a paginated table or a visualization, and how many rows it has. Neither is stored today: the output mode comes from the engine's physical plan, which only exists in the CU, and the row count is obtained by opening each result table. `operator_port_executions` records only the URI and size. **Scope** - Add `output_mode` and `result_count` to `operator_port_executions` (`sql/updates/52.sql` and `texera_ddl.sql`). - Record the output mode when the port's result URI is persisted (`persistOperatorPortResultUri`), from the output port's declared mode. - Record the row count when the execution finishes, next to where `result_size` is written today. Rows written before this change have both columns null; readers treat a null mode as a table and a null count as unknown. **Out of scope.** Reading these columns, which is the result-service task. ### Task Type - [ ] Refactor / Cleanup - [ ] DevOps / Deployment / CI - [ ] Testing / QA - [ ] Documentation - [ ] Performance - [x] Other -- This is an automated message from the Apache Git Service.
