Expose Domain/Mode Dropdowns as Inputs in Nodes

Currently, dropdown menus in Geometry Nodes (such as “Domain” in For Each Element, or “Mode” in a lot of other nodes) cannot be exposed as inputs.

This means that if I want the same setup / node group to work with different modes/domains (e.g., Point, Edge, Face, Instance), I have to duplicate the same setup for each variant.

Proposal: Allow these dropdowns to be promoted to inputs. This would make setups more flexible, easier to automate, and reduce unnecessary duplication of node networks.

Something similar to the “Switch” node menu input would be perfect — so we could dynamically select the mode/domain from outside the node.
