fix: Worker detection

[rschristian]

Workers must have .worker in their name yet this regex didn't test for it. So new URL('./foo.js', import.meta.url) is (incorrectly) treated as a worker.

This behavior is still super sketchy and flawed, as a simple console.log(new URL('./foo.worker.js', import.meta.url)) will trigger (in prod, in dev the user will just get errors) WMR to emit another file, but this at least reduces the chances of users running into it.
