Returns the live breaker state for one owner-and-host scope, creating it
on first use.
Access refreshes the scope's recency in the per-owner map; once an owner
tracks more scopes than the LRU cap allows, the least-recently-used
scope's state is evicted so dynamic-URL callers cannot grow the map
without bound. Disabled configurations never reach this function, so
opting out allocates nothing.
