Extract DelegateRefresher to deduplicate JSON resource wrapper logic#1870
Conversation
JSONURLFilterWrapper and JSONResourceWrapper contained near-identical code for loading a delegate class, validating it implements JSONResource, and setting up a periodic refresh timer from OpenSearch. This extracts the shared logic into a generic DelegateRefresher<T> class, reducing each wrapper from ~180 lines to ~75 lines. Adds 8 unit tests for the new class.
