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.

Fix a deadlock in the log-stream handler that caused all logs
requests to hang: Connection used a single Mutex<JsonFramed> for
both reads and writes, so the serve loop holding the read lock
blocked the spawned notification task from writing. Split
Connection into separate reader and writer mutexes.
Also fix a response/notification ordering race: the log task now
waits for an explicit ready signal sent by serve after writing the
LOGS response, ensuring notifications never arrive at the client
before their initiating response.
Replace bail!("not implemented") stubs with real RPC calls over the Unix
socket; add format::list_table for fixed-width list output.

Implement per-connection ConnState tracking active subscriptions, and the
logs/logs_cancel RPC handlers. Snapshot-only streams terminate with a
log_end notification; follow streams forward broadcast lines until
cancelled or connection close.

Implements the `reload` JSON-RPC method: diffs the on-disk config dir
against the in-memory registry and reconciles — stops removed servers,
restarts changed servers (shutdown-then-respawn), and starts new ones.

Per-connection JSON-RPC dispatch in daemon/handlers.rs — list, status,
start, stop, and restart are fully implemented; reload, logs, and
logs_cancel are stubbed with -32601 for later tasks.

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*).

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.
