Roadmap and status for non-English language support (FR, ES, IT, DE, etc.)

Hi, First of all, great work on Harper. The project looks extremely promising and feels like a very solid alternative to existing solutions such as Grammarly or LanguageTool, especially in terms of performance, privacy, and overall philosophy. At the moment, Harper only supports English. I have tried to look through the documentation, the README, issues, and discussions, but I could not find clear information about the status or roadmap regarding support for other languages. I would love to understand a few things: - Is support for other languages (for example French, Spanish, Italian, German) planned at some point? - Are there already people actively working on non-English language support? - Is the core architecture considered mature enough for external contributors to realistically add new languages? - If not planned, is this more a matter of priorities, resources, or inherent complexity? I think it is a bit unfortunate that there is no clear, centralised information about this topic, because Harper is really exciting and could be extremely attractive to non-English users if multilingual support were on the horizon. Thanks again for building such a great tool, and thanks in advance for any insight you can share. Best regards,
