The agent-runtimes repo is moving to a CRS-only harness model: dispatcher
images stop baking in /app/harnesses/ and discover them via CRS at runtime.
cp-harness was the only harness that lived only in the agent-runtimes
checkout (created in M16 Phase 1 D4, commit c1df4cc) — copied here so
nothing is lost in the cutover.
cp-harness has no current consumers (no composite or template references
it); it is infrastructure for the future M16 self-orchestration api_key
submission flow.
