Add a CLI tool and Go library that speak the libtpu checkpoint/restore control protocol (pkg/sentry/control/tpu_control.proto) against unsandboxed processes. gVisor coordinates libtpu C/R during sandbox save/restore (pkg/sentry/control/tpu_control.go), but there is no way to exercise or debug that protocol path without a full runsc save cycle. This tool fills the gap: it discovers libtpu control threads by scanning /proc/<pid>/task/*/comm, opens the encoded pipe FDs via /proc/<pid>/fd/, and sends ControlRequest messages. Accepts a comma-separated PID list and runs actions concurrently across PIDs with per-PID results, for multi-process jobs that need all processes checkpointed together.
