+        Atomically commit a batch of table operations. This is a generalized version
+        of `BatchCreateTableVersions` that supports mixed operation types within a
+        single atomic transaction at the metadata layer.
+
+        Supported operation types:
+        - `DeclareTable`: Declare (reserve) a new table
+        - `CreateTableVersion`: Create a new version entry for a table
+        - `DeleteTableVersions`: Delete version ranges from a table
+        - `DeregisterTable`: Deregister (soft-delete) a table
+
+        All operations are committed atomically: either all succeed or none are applied.
