- Remove 'USER hermes' from Dockerfile so entrypoint runs as root and can
usermod/groupmod before gosu drop. Add chmod -R a+rX /opt/hermes so any
remapped UID can read the install directory.
- Fix entrypoint chown logic: always chown -R when HERMES_UID is remapped
from default 10000, not just when top-level dir ownership mismatches.
- Add docker-compose.yml with gateway + dashboard services.
- Add .hermes to .gitignore.
