feat: add docker-compose deployment and harden gateway startup

- add docker-compose setup with hermes-agent + hermes-webui

- make runtime config env-driven (compose vars + HERMES_BIN)

- improve gateway startup/restart resilience in docker

- make base image configurable via BASE_IMAGE/HERMES_AGENT_IMAGE
