feat(hermesagent): add hermes-setup helper script for first-time setup

- Add /usr/bin/hermes-setup that runs hermes setup as root, allowing
  optional components (TTS engines, browsers, etc.) to be installed,
  then restores ownership and permissions on /home/hermes
- Update login hint to reference hermes-setup
- Update completion message to guide users to hermes-setup and note
  that the gateway service should be installed as a user service
- Update JSON note to reflect new setup flow
