• Persist a lang field in config get/set and in the HTTP server
• Add a dropdown in the web UI and reload on language change
• Extend CLI lang command, update client code, tests, and translation keys

Comments suppressed due to low confidence (3)

src/commands/lang.js:19

• The command’s cache update logic inside the try block isn’t covered by existing tests. Add tests to ensure the CLI lang command persists the new language in appCache.

  try {

public/components/views/settings/settings.js:234

• This assignment reverts the updated lang back to the old value. You should assign this.config = newConfig so the new language persists in the component state.

    this.config = { ...newConfig, lang: this.config.lang };
