A plain new Worker("./w.js") or navigator.serviceWorker.register("./sw.js")
resolves against the document base URL in a browser, and a Node
worker_threads string resolves against the working directory. Static
analysis was resolving browser strings against the calling script, which
recorded a resolved mapping to the wrong file.
Only new Worker(new URL(path, import.meta.url)) now produces a specifier.
Other worker and service-worker strings keep their expression and stay
unresolved, matching the existing worker_threads string handling.
Fixes#3309
