Add HVTracker badge to README?

[YugantM]

Hi maintainers — HVTracker currently ranks OpenAI Agents SDK #5 with an HVTrust score of 90.1/100 and evidence grade B.

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

Profile: https://hvtracker.net/agents/openai-agents-sdk/

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.
