Records browser responses to disk and replays them on later runs. When
`httpCache: { dir, match }` is set, the runner starts a single caching
MITM proxy and routes all browsers through it. GET/2xx responses are
stored verbatim (raw bytes + headers) and matched by an optional URL
glob/regex; https is intercepted with a self-signed cert. One proxy owns
the cache for the whole run, so all workers share it and concurrent
identical misses coalesce into one upstream fetch.

There was a problem hiding this comment.
I'm not seeing typical caching headers like Vary or Accept-Encoding be mentioned, which seems fishy. Am I misunderstanding something?
