Walkthrough

The pull request adds a workflow step to .github/workflows/reusable-homebrew-tap.yaml that checks out the release repository before downloading release assets. This ensures the repository context is available when subsequent gh release download commands execute in the update-formula job.

Poem

🐰 A checkout step hops into place,
Before the assets download with grace,
Repository context, now sure and true,
The workflow path grows stronger too! 🐇
