§In-memory ClientStorage implementation
A HashMap<String, HashMap<String, Entry>> that implements the
crate::client::client_storage::client_storage::ClientStorage trait. Each inner map is
one bucket; each Entry carries the compressed value and a last_accessed timestamp.
When a bucket exceeds its crate::client::client_storage::client_storage::BUCKET_TRIMS
cap, the oldest-accessed entries are dropped.
Used by tests (including the integration-test harness) and by any deployment that explicitly opts out of on-disk persistence.
