When recycling rowset data, the recycler treated a missing versioned delete bitmap meta key as "not packed" and added the standalone delete bitmap object path to the delete_files request. This caused unnecessary delete object requests for `<rowset_id>_delete_bitmap.db` even when no delete bitmap storage metadata existed. The fix makes delete bitmap storage handling explicit: missing meta, FDB storage, standalone file storage, and packed file storage are distinguished. The recycler now only deletes `<rowset_id>_delete_bitmap.db` when the metadata explicitly indicates a standalone delete bitmap file.
