Walkthrough

The PR adds a condition to the GitHub Actions workflow that prevents coverage regression checks from running on Dependabot pull requests, complementing the existing conditions that gate the check to non-main, non-tag refs.

• DefangLabs/defang#1988: Both PRs modify the .github/workflows/go.yml "Check coverage regression" logic—the prior PR adds the coverage regression gate, and this PR further extends its skip conditions to exclude Dependabot runs.
• DefangLabs/defang#2114: Both PRs adjust GitHub Actions behavior specifically for dependabot[bot] runs.

Poem

🐰 Dependabot sends pulls with care,
But coverage checks need not compare,
One line added, gating clean,
Skips the noise, just keeps the scene! ✨
