Keep tool-result dumps out of the deliverable gate and cards

Why: The live after-run (golden minutes-pm-tool) showed the truncation spill
artifact tool-run_shell-<call>.txt entering CheckArtifacts as a .txt
deliverable; its non-UTF-8 payload failed the scorer four times in a row.
These files exist to keep oversized tool output reachable - they are context
relief, not deliverables, and must not occupy delivery cards either.

Evidence: SELF - TestLatestDeliverablesKeepsLastPerName extended with a
tool-dump ref and asserts exclusion; go test ./internal/... passes; single-task
live rerun recorded on the phase02 task card.

Impact: latestDeliverables (gate input, verifier refs, reply deliverable list,
final artifact_ref cards) skips kind=data tool- prefixed refs. The spill files
remain artifacts for context backfill.
