When the HTML parser blocks on a synchronous external script, run a separate tokenizer over the unparsed input and issue speculative fetches for the resources it finds (script src, link rel=stylesheet|preload, img src), with <base href> tracking and template/foreign-content skipping. Also fills in the previously-stubbed "consume a preloaded resource" algorithm and the document's "map of preloaded resources", so that <link rel="preload"> followed by a matching consumer deduplicates to a single fetch.
