Document and test governed-runner inspection facade

[mdheller]

Summary

Documents and tests the product-facing governed-runner inspection commands now exposed by AgentPlane through sp-run.

These remain pure facade delegations:

prophet governed-runner list --runs-root ./.socioprophet/smoke/governed-runner
prophet governed-runner status ./.socioprophet/smoke/governed-runner/run
prophet governed-runner inspect ./.socioprophet/smoke/governed-runner/run

Delegates to:

sp-run list --runs-root ./.socioprophet/smoke/governed-runner
sp-run status ./.socioprophet/smoke/governed-runner/run
sp-run inspect ./.socioprophet/smoke/governed-runner/run

Adds

• README examples for run-store inspection commands
• tests/test_governed_runner_inspection_facade.py

Boundary

No governed-runner implementation moves into prophet-cli. This only documents and tests the facade path after AgentPlane added the actual sp-run list/status/inspect commands.

Validation

pytest -q
