httpcache: write <path>.meta JSON sidecar after each successful download; load it on first Fetch so conditional GETs work after process restarts. Tests verify: download, sidecar written, same-cacher 304, fresh-cacher 304 (the last being the key case — no in-memory state, sidecar drives ETag). MaxMind integration test reads GeoIP.conf, downloads City+ASN, verifies fresh-cacher conditional GET skips re-download via sidecar ETag.
