Tests Failing Badge in README Points at All Tests Running Through `ci.yml`

Right now, this badge is appearing in the README:

<img width="97" height="20" alt="Image" src="https://github.com/user-attachments/assets/fc8d21c6-10d2-4f7d-b34f-a4f5471871d2" />

It's currently failing because I opened a Draft pull request that is failing.  If we have a badge like this, it should only apply to merges to `main`, right?
