Cursor / GraphQL-connection-style pagination for the Paginator pagination library. Provides CursorPaginator, MutableCursorPaginator, CursorPagingCore, CursorPaginatorPrefetchController, the cursor DSL, eviction strategies, and the cursor serialization layer. Builds on paginator-core. Pick this module for feeds keyed by opaque cursors (Relay-style next/prev tokens); for classic page-number feeds use paginator-offset instead.
