fix: address Hermes review findings (5 medium issues)

- Add missing Hermes MCP import on first launch (lib.rs)
- Add Hermes branch in ProviderForm defaultValues fallback
- Include Hermes in session manager subtitle (zh/en/ja)
- Rename check_openclaw_stream to check_additive_app_stream
- Cache parsed HERMES_DEFAULT_CONFIG to avoid repeated JSON.parse
