Run the Docker-backed @repo/sandbox-execution process-lifecycle suite in CI so the supervisor's process-group and orphan-reaping guarantees are enforced, not just asserted once by hand.

Process-tree supervision and Tini-backed reaping are exactly the kind of guarantee that rots silently: a regression would not surface until a real sandbox leaked zombies in production. This wires the lifecycle suite into the reusable quality workflow, extends the path filters so it triggers on execution-substrate changes, declares its inputs in turbo.json for correct caching, and — because the guarding config is only useful if it stays correct — extends the quality-config guard to assert the new wiring.

Depends on the SDK process PR (its actual parent) and builds on the config guarded by naresh/quality-config-guard. No source overlap with the other migration PRs; retarget to next once the core stack merges.
