## Ejemplo

```go
conn := SSHConn{Host: "185.x.x.x", User: "root"}
cfg := DeployConfig{
    AppName:    "dag_engine",
    LocalDir:   "apps/dag_engine",
    RemoteDir:  "/opt/apps/dag_engine",
    BinaryName: "dag_engine",
    BuildCmd:   "CGO_ENABLED=0 GOOS=linux go build -o dag_engine .",
    Port:       8080,
    HealthPath: "/api/health",
}
err := DeployAppRemote(conn, cfg)
```

## Notas

Pipeline de 5 pasos para deploy continuo (asume que el setup inicial ya se hizo con `setup_vps_app`). El build corre localmente en `LocalDir` con `bash -c BuildCmd`. Si `BuildCmd` está vacío, se salta el build y sube directamente el binario existente.
