<!-- Thanks for sending a pull request! --> <!-- Please make sure you have read and understood the contributing guidelines --> **What this PR does**: Support semicolon-separated MySQL DML statements in AT mode through a validated execution plan. The plan provides two execution paths: - **Aggregate execution**: executes eligible same-table, non-parameterized `UPDATE` or `DELETE` statements together and builds aggregated before/after images. - **Sequential execution**: executes multiple `INSERT` statements, mixed DML, parameterized statements, and statements targeting different tables in order, while reusing the existing single-statement executors. This PR also: - validates all child statements and arguments before executing business SQL. - rejects unsupported `UPDATE JOIN`, MySQL multi-table `DELETE`, and prepared multi-SQL. - falls back to prepared execution when the driver returns `driver.ErrSkip`. **Which issue(s) this PR fixes**: <!-- *Automatically closes linked issue when PR is merged.
