fix: shouldSkipRedirect incorrectly skips cross-domain redirects

[devinle]

Summary

• Adds host comparison check in shouldSkipRedirect to ensure cross-domain redirects are never skipped
• Fixes an issue where redirects configured from one domain to another with the same pathname would result in 404 errors instead of proper redirects

Fixes #941

Changes

packages/core/src/utils/fetchRedirect.ts:

• Added early return in shouldSkipRedirect when linkURL.host !== redirectURL.host
• Cross-domain redirects now bypass the pathname comparison logic and are properly followed

Test plan

• Added test for cross-domain redirect with same pathname
• Added test for cross-domain redirect with different pathname
• CI tests pass

Note

Low Risk
Small, well-scoped change to redirect-skipping logic with added test coverage; limited to redirect resolution behavior.

Overview
Fixes fetchRedirect incorrectly treating cross-domain redirects as skippable when the pathname/query matches, by adding a host comparison so cross-domain redirects are always followed.

Adds MSW handlers and unit tests covering cross-domain redirects with both identical and different pathnames, and includes a patch changeset for @headstartwp/core.

🎉 Global Bundle Size Decreased

Page	Size (compressed)
global	83.62 KB (🟢 -42.45 KB)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
