Cut v0.37.0 release to activate eval measurement manifests

[fullsend-ai-triage]

Summary

PR #722 merged measurement manifests (eval/measurements/*.yaml) into main, but the floating v0 tag still points to v0.36.0 (published 2026-08-11), which predates that merge.

A new v0.x.y release is needed so that v0 resolves to a SHA that contains the manifests. Without this, managed eval-measure jobs clean-skip because the remote manifest lookup against fullsend-ai/agents@v0 finds no eval/measurements/ files.

Acceptance

• v0.x.y release cut (e.g., v0.37.0)
• v0 tag re-pointed to the new release SHA
• Verify: eval/measurements/*.yaml files are present at the SHA that v0 resolves to
