fix: return nil instead of err variable in isLocalhost success path

[k1LoW]

This pull request makes a small fix to the isLocalhost function in http.go. The change ensures that when a loopback IP is detected, the function returns nil for the error instead of propagating a previous error value.

Summary of Changes

Hello @k1LoW, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the error handling within the isLocalhost function. The change ensures that when a local loopback address is successfully identified, the function correctly signals success by returning a nil error, rather than inadvertently returning an error that might have occurred earlier in the function's execution. This improves the robustness and clarity of the function's output.

Highlights

• Error Handling Correction: The isLocalhost function was updated to explicitly return nil for the error value when a loopback IP is successfully detected. This prevents the propagation of a potentially stale or incorrect error from previous operations within the function.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request correctly addresses an issue in the isLocalhost function. By returning nil for the error when a loopback IP is successfully identified, the function now accurately reflects a successful outcome without propagating a potentially stale or irrelevant error value. This improves the correctness and clarity of the error handling in this specific success path.
