Compare the normalized registry origin.

The raw prefix check does not block https://registry.npmjs.org without the trailing slash. Equivalent URL spellings can also bypass the check before fetch normalizes them. If the wrapped code supplies one of these forms, the request reaches the public registry and the startup wait can recur. Parse the URL and compare its normalized origin with https://registry.npmjs.org.

Review comment at @test/js/third_party/next-auth/fixture/server.js at line 52:
Update the registry check in the fetch wrapper to parse the input as a URL and
compare its normalized origin with https://registry.npmjs.org. Block matching
requests regardless of trailing slashes or equivalent URL spellings, while
preserving the existing behavior for other origins.

Add direct regression coverage for both fetch-wrapper branches.

next-auth.test.ts starts the fixture and checks its output and exit status, but it does not assert that registry URLs are rejected or that non-registry URLs delegate to the captured fetch. Add these branch-specific assertions to the existing test file through the fixture's test entry point.
