The `done` channel closes on exit; use `<-proc.Done()` or `proc.Wait()`. - **Detach / process group isolation**: Set `RunOptions.Detach = true` to run the subprocess in its own process group (`Setpgid`). Detached processes use `context.Background()` so they survive parent context cancellation and parent death. - **Graceful shutdown**: `Service.OnShutdown` kills all running processes. `Daemon.Stop()` performs ordered teardown: sets health to not-ready → shuts down health server → releases PID file → unregisters from registry. `DaemonOptions.ShutdownTimeout` (default 30 s) bounds the shutdown context. - **Auto-registration**: Pass a `Registry` and `RegistryEntry` in `DaemonOptions` to automatically register the daemon on `Start()` and unregister on `Stop()`. - **PID liveness checks**: Both `PIDFile` and `Registry` use `proc.Signal(syscall.Signal(0))` to check if a PID is alive before trusting stored state. -- **Error handling**: All errors MUST use `coreerr.E()` from `go-log` (imported as `coreerr`), never `fmt.Errorf` or `errors.New`.
