chore: retrigger CI — Local Provision E2E stub failed on provisioning timeout (infra flake on main, unrelated to dead-code removal)

QueueDepth was added for Phase 2/3 busy-return response visibility but
was never wired to a caller. The inline depth query in EnqueueA2A serves
today's enqueue response, making this function dead code.
