Cached responses incorrectly become stale under min-fresh because the calculation uses epoch time; max-stale is read from the original request instead of the current one. Apply both directives to the cached response's age, as required by RFC 9111. This builds on the cache-age and exact-expiration fixes in uv#20178 and uv#20183.

⚠️8 benchmarks spent significant time in system calls
System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.
No successful run was found on main (8dcc24e) during the generation of this report, so 1a2544a was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
