Multiple Hermes installations on the same machine now get unique systemd service names: - Default ~/.hermes → hermes-gateway (backward compatible) - Custom HERMES_HOME → hermes-gateway-<8-char-hash> Changes: - Add get_service_name() in hermes_cli/gateway.py that derives a deterministic service name from HERMES_HOME via SHA256 - Replace all hardcoded 'hermes-gateway' systemd references with get_service_name() across gateway.py, main.py, status.py, uninstall.py - Add HERMES_HOME env var to both user and system systemd unit templates so the gateway process uses the correct installation - Update tests to use get_service_name() in assertions
