Function createConfigService

createConfigService(options: ConfigServiceOptions): ConfigService
Create a NAP-CONFIG reference service.

Shell-writes, napplet-reads. Handles the full @napplet/nap/config wire protocol: config.get (correlated snapshot), config.subscribe / config.unsubscribe (live push stream), config.registerSchema (optional schema registration + Core Subset validation), config.openSettings (optional UI deep-link, fire-and-forget).

Returns a ConfigService bundle: { handler, publishValues }. Register handler with the runtime; call publishValues(newValues) from the shell whenever config state changes.
Parameters
- options: ConfigServiceOptions
  Host-supplied implementation hooks (options-as-bridge, v1.6 Decision 18). getValues is required; all other fields are optional.
Returns ConfigService
A ConfigService bundle.

});
runtime.registerService('config', config.handler);

config.publishValues({ theme: 'light', density: 'compact' });
