feat: SiliconFlow async data generator (Qwen2.5-72B, 5-way concurrent, dedup+resume)
- Hard-codes SiliconFlow API key and Qwen/Qwen2.5-72B-Instruct model
- SHA256 fingerprint deduplication across (category, user_input[:80], ai_response[:80])
- Deficit-weighted category balancing across all 10 risk categories (R1–R10)
- Resume capability: reads existing output file, skips already-generated samples
- Exponential backoff on rate limits and API errors
- Rich CLI: --total, --output, --safe-ratio, --concurrency
