copilot-swe-agent[bot] 91dd15d3bf Fix batch size check to only apply to atomic batches with tests
The verify_batch_size() check was applied to all batches before determining mutate_atomic, causing unnecessary failures for batches that never touch system.batchlog. Only logged multi-partition batches (mutate_atomic=true) are stored as blobs in system.batchlog and require size validation.

Changed:

* Moved verify_batch_size() call in execute_without_conditions() directly
  into the logged multi-partition branch for clearer intent
* The check is now placed exactly where mutate_atomic=true, making the
  code more intuitive

Result:
Batch Type  Single-Partition  Size Check
LOGGED      false             YES
LOGGED      true              NO
UNLOGGED    N/A               NO

Tests:

* test_unlogged_batch_size_not_checked: Unlogged batch >1024KB succeeds
* test_logged_multi_partition_batch_size_checked: Logged multi-partition batch >1024KB fails
* test_logged_single_partition_batch_size_not_checked: Logged single-partition batch >1024KB succeeds

Fixes #27605
