- Add DevToolBootstrapSettings under DevToolSettings for process-local iOS bootstrap values, including Lynx debug and LogBox defaults.
- Route LynxEnv through bootstrap settings instead of reading default policy from LynxServiceDevToolProtocol.
- Keep the deprecated service preset properties as compatibility APIs, with concrete DevTool services forwarding them to DevToolSettings.
- Update Explorer to apply development bootstrap defaults through settings while preserving DebugRouter session enablement in the service path.
