Generic selectors for workflow overlays

[markuswondrak]

Workflow overlays currently target steps by explicit ID. This requires repeating the same edit for every matching step when a cross-cutting behavior is needed.

Would generic overlay selectors be a relevant feature?

Potential requirements:

• Select multiple existing steps by attributes such as  type  (gate, command) or other predicates.
• Apply insert_before, insert_after, replace, or remove to every match.
• Preserve deterministic ordering and unique step IDs.
• Define behavior for nested steps and steps introduced by other overlays.
• Keep existing ID-based anchors and overlay precedence unchanged.

Example use case: attach the same step after every gate without enumerating each gate ID.
