docs: add prominent AGPL-3.0 attribution to upstream clawd-on-desk

- README.md: add license + upstream badges, dedicated 致谢/Attribution
  callout near the top, expanded License & Acknowledgments section at
  the end with AGPL §13 network-service notice and source URL.
- README.md: docs index entry for clawd-on-desk/AGENTS.md now links to
  the upstream rullerzhou-afk/clawd-on-desk repository directly.
- CONTRIBUTING.md: note that clawd-on-desk/ is a vendored AGPL-3.0 fork
  of rullerzhou-afk/clawd-on-desk and clarify upstream compatibility in
  the License section.

NOTICE.md / LICENSE / clawd-on-desk/{LICENSE,NOTICE.md} were already
in place and remain authoritative for the full attribution chain.
