feat: Add Qwen OAuth cross-platform import for ALL Claw platforms

Key Feature: Use FREE Qwen tier (2,000 req/day) with ANY platform!

How it works:
1. Get Qwen OAuth: qwen && /auth (FREE)
2. Extract token from ~/.qwen/
3. Configure any platform with token

Supported platforms:
- OpenClaw ✅
- NanoBot ✅
- PicoClaw ✅
- ZeroClaw ✅
- NanoClaw ✅

Configuration:
  export OPENAI_API_KEY="$QWEN_TOKEN"
  export OPENAI_BASE_URL="https://api.qwen.ai/v1"
  export OPENAI_MODEL="qwen3-coder-plus"

Added:
- import-qwen-oauth.sh script for automation
- Cross-platform configuration examples
- Qwen API endpoints reference
- Troubleshooting guide

Free tier: 2,000 requests/day, 60 requests/minute
