Workflow "v2 run" handles are scaffolded but never created

Workflow records can hold a newer run handle, but nothing ever creates one here.

v2 workflow run handles and schema extensions are scaffolded but the provider returns nothing.

What

Workflow task records can now hold a v2 run handle that gets killed when the workflow is stopped, and the workflow tool's output schema is meant to absorb extra fields from a provider. That provider compiles to a bare return;, so no extra fields are added and no v2 run is ever created here.

Evidence

runOpOutputFields

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
