Resolved conflicts:
- package.json: Keep local version (@openclaw/qqbot 2026.1.31)
- src/api.ts: Keep local comments
- src/gateway.ts: Keep local features (qqimg tag support, local file handling, 60s timeout)
- src/outbound.ts: Keep local implementation (rate limiting records)
- README.md: Accept upstream version
