Add HVTracker badge to README?

Hi maintainers — HVTracker currently ranks Codex #2 with an HVTrust score of 91.5/100 and evidence grade C.

If useful, would you be open to adding the live HVTracker badge to your README so users can inspect the trust profile directly?

Markdown snippets:

[![HVTrust](https://hvtracker.net/badge/codex.svg)](https://hvtracker.net/agents/codex/)
[![Evidence Grade](https://hvtracker.net/badge/codex-grade.svg)](https://hvtracker.net/agents/codex/)

Profile: https://hvtracker.net/agents/codex/

Totally fine to close if this is not useful — just thought it might be helpful for maintainers who want an independent trust/status link in their repo.
