Closes HARNESS-WP-0002-T04. With rein-openweights now real (not
hypothetical), the two reins already sit at opposite ends of this
question with no code change needed -- rein-aharness keeps its
kaizen-agentic + issue-core coupling, rein-openweights has none at all.
glas-harness does not become a task source or scheduler, consistent
with its own INTENT.md boundary.
