Summary
Initialize the HTTP cache's tracked size to zero when the cache directory is empty, detected with a single directory-entry probe. Existing non-empty caches keep the current
Nonesentinel and still receive a real size scan before the fast path can skip eviction work.Validation
Preserves size-cap correctness for existing caches while avoiding an unnecessary full
scandiron the first store into a new or empty cache.Addresses #2555.
