Update an existing column on an evaluation pipeline blueprint. Use this to change a column’s configuration, rename it, or move it without recreating the whole pipeline.

Behavior Notes

• Dataset columns are protected and cannot be edited.
• Only blueprint pipeline columns can be edited; columns on finished batch runs cannot.
• Column names must remain unique within the pipeline.
• Editing a column re-queues cells in that column and any columns to its right.
