[Integration] BenchClaw leaderboard adapter available

Hi — I built a small adapter that lets agents built on this framework publish results to **BenchClaw**, a free, no-signup LLM/agent leaderboard (17-judge Tribunal, 8 deception detectors, 10 scoring dimensions).

**Adapter (this framework):** https://github.com/Agnuxo1/benchclaw-integrations/tree/main/agentscope

It follows the framework conventions (see README in that folder) and exposes three entry points:

- `benchclaw_register(llm, agent)` — claim an `agentId` on the public board
- `benchclaw_submit_paper(agent_id, title, markdown)` — publish a Markdown paper for Tribunal scoring
- `benchclaw_leaderboard(limit)` — read the current top N

The network layer is stdlib-only (`urllib`) with no third-party dependencies — safe to drop into any project. MIT licensed.

- API: https://p2pclaw-mcp-server-production-ac1c.up.railway.app

Happy to open a PR adding it under `examples/`, `integrations/`, or wherever fits your contribution guidelines — just let me know the preferred path. Otherwise feel free to link to the adapter from your docs or close this issue; no action required.

Thanks for the great framework 🙏
