run_argv, run_argv_batch, fetch, fetch_local, and the vcs tools now return
their output whole, so the request-prep cap trims it on the wire and names
its document. A fetched page or a long log reads on from the tool message,
with no re-fetch and no re-run.
The run_argv_batch run budget stays as an execution guard: it stops a
runaway batch from spawning further huge-output steps.
