Adds docker-compose.two-container.yml and README section for running
hermes-agent and hermes-webui in separate Docker containers connected
via shared volumes.
The key insight: the WebUI imports hermes-agent's Python modules
directly (not via HTTP), so the agent source must be mounted into
the WebUI container. The existing docker_init.bash handles installing
the agent's dependencies at startup via uv pip install.
Shared volumes:
- hermes-home: config, sessions, skills, memory (~/.hermes)
- hermes-agent-src: agent source code for Python import
Fixes#288
