Add StartAck::SpawnFailed(String) so callers can distinguish a successful
start from a failed spawn. The Start command arm now sends SpawnFailed on
io::Error rather than the misleading Started. handlers.rs maps the new
variant to an RpcErrorCode::SpawnFailed JSON-RPC error response.

Replace the bare sleep(delay).await in the Restart backoff arm with a
tokio::select! over the timer and cmd_rx. Stop/Shutdown are now handled
immediately during backoff (Stop → Stopped, Shutdown → clean exit);
Start/Restart/Reconfigure skip the remaining delay and retry at once.

Replace watch::Receiver<ServerState> on SupervisorHandle with watch::Receiver<Status>,
a richer snapshot type that carries pid, port, uptime_secs, restart_count and last_exit.
SupervisorTask maintains current_pid and publishes a fresh Status on every state
transition; handlers.rs reads the full Status so list/status no longer return
zeroed/None fields.

One async task per managed server owns all state transitions via a
tokio::select! loop over cmd_rx and wait_child. Includes RealSpawner
and a smoke test covering the Start → Running → exit → Stopped →
Shutdown happy path.

Append RealChild (real tokio::process::Child wrapper) and spawn_with_logs
to child.rs. Uses nix::unistd::setpgid via tokio's re-exported pre_exec
to create an own process group, and fires per-stream log pump tasks that
drain stdout/stderr into the provided LogSink. terminate/kill signal the
whole process group via kill(-pgid, SIG*).
