Feature Request: Quibble language setting (multi-language support)

Feature Request

Quibble (the axolotl companion in the input box) currently only speaks English. It would be great to have a language setting so Quibble can speak in the user's preferred language.

Use Case

I work in a multilingual environment (German, French, English) and all my interactions with Claude Code are in German or French. Quibble's English-only comments feel disconnected from the conversation.

Proposed Solution

A setting in ~/.claude/settings.json or similar, e.g.:

{
  "quibble": {
    "language": "de"
  }
}

Or ideally: Quibble auto-detects the conversation language and responds accordingly.

Alternatives

• Auto-detect from the LANG environment variable
• Follow the language of the last user message
• A /quibble language de command

Thank you!
