Hugging Face Space — online demo

Create a Hugging Face Space with a Gradio UI for trying argus-redact online.

**Features:**
- Text input box
- Language selector (zh/en/ja/ko/de/uk/in)
- Mode selector (fast/ner)
- Show redacted text + key + restored text side by side
- No Ollama needed (just regex + NER)

This would let people try argus-redact without installing anything.
