Reviewer's Guide

This PR updates the release GitHub Actions workflow to ensure protoc is installed via a dedicated setup action before Go is configured and the build runs.

Hey - I've found 1 issue, and left some high level feedback:

• Consider pinning arduino/setup-protoc@v3 to a specific commit SHA (or at least a minor version) to reduce the risk of unexpected changes in the action impacting the release workflow.
• If the workflow only needs public artifacts, evaluate whether repo-token: ${{ secrets.GITHUB_TOKEN }} is strictly required and, if so, document why the default token permissions are sufficient for this step to keep the token usage minimal.

**suggestion (bug_risk):** Consider pinning protoc to a specific version for reproducible builds

Using a floating version like "25.x" means builds can silently change when new minor releases are published, potentially introducing regressions. Pinning to a specific version (e.g., "25.3") keeps builds deterministic and ensures changes only occur when you explicitly update the version.

```suggestion
      - name: Install protoc
        uses: arduino/setup-protoc@v3
        with:
          # Pin protoc version for reproducible builds; update explicitly as needed
          version: "25.3"
          repo-token: ${{ secrets.GITHUB_TOKEN }}
```
