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*).

Adds kdl_parse module with parse_server_config() that deserialises a
KDL document into ServerConfig, with full validation of name, types,
durations, and restart/stop blocks. Also derives Default on
RestartPolicy to satisfy clippy.
