Speculative fetch/connect before service worker loads

Description

Currently we wait until the service worker is installed and the page reloaded before doing lookup operations like routing lookups, IPNS resolution, or DNSLink resolution from delegated-ipfs.dev. It might be a good idea to use prefetching to start the lookups while the service worker is still being processed and installing to reduce net time for users to load their content.

Similarly we could choose to pre-connect to trustless-gateway.link in the event that we need it.
