Keep clone files and oversized responses out of the cache
The dumb transport reads files that already sit on the disk, so a pack copied into a slot cost that disk twice and the request a second write of every byte. A snapshot took a slot whatever its size, so a visitor naming distinct refs and ids could fill the cache root with archives. `cache-max-slot-size`, 64 MB unless set, now serves a larger response from the lock file and drops it, along with any expired copy it would have replaced.
