feat(deploy): despliegue nativo Debian sin Docker

- Elimina todos los Dockerfiles y docker-compose.yml
- Elimina scripts Docker (start_docker, reset_and_deploy, deploy-clean)
- Agrega deploy/debian/ con despliegue nativo via systemd:
  - install.sh: instalacion completa en Debian (PostgreSQL, Redis,
    Qdrant binario, Go, Python venv, nginx, frontend compilado)
  - build.sh: recompila binarios Go y frontend sin reinstalar
  - env.example: variables de entorno sin referencias Docker
  - nginx.conf: sirve React estatico + proxy al API Go en localhost
  - systemd/*.service: 16 servicios (8 Go + 7 Python + Qdrant)

Todos los hostnames Docker (db, redis, qdrant) reemplazados por 127.0.0.1
