Ville Vesilehto 4ca99cd7b6 fix(cache): isolate metadata in prefetch goroutine (#7631) ...

Wrap doPrefetch with a fresh metadata context to prevent concurrent
writes to the request-scoped metadata map during background prefetch.

Add a new integration test configuring a plugin chain, triggering
the issue seen here. Hammers concurrent queries while log reads
metadata fields repeatedly.
