Every production process spawn reachable from a tokio worker now uses
tokio::process: the install path's podman-port probe, the dependencies
disk check, factory-reset restart, config host-IP detection, the
orchestrator's host-facts helpers (resolve_dynamic_env and its call
sites made async to carry it through), and AutoRuntime's podman/docker
probes.
The FIPS transport probe is the special case: is_available() is a sync
trait method called from async route(), so instead of blocking ~50ms
on systemctl per stale-cache hit it now serves the cached value and
refreshes on a background thread (stale-while-revalidate) — bounded
staleness, zero stalled workers.
§C of the 1.8.0 hardening plan; container/transport/config/package
suites green.
