+     * @class CursorManager
+     * @brief Orchestrates data pagination from storage backends to the query executor.
+     *
+     * The Cursor Manager implements the glue between the 'registry' objects
+     * and the Volcano-style iterator model. It translates high-level plan
+     * requests into low-level backend operations (LMDB, etcd, etc.).
+     *
+     * DUTIES:
+     * 1. Snapshot Anchoring & Pins:
+     *    We need to bind the retrieval to a multigroup snapshot, the object
+     *    for it should hold the reference for the tree that holds all the relations and tuples.
+     *
+     * 2. State Maintenance:
+     *    Tracks the current position (Iterators/Offsets) within a relation
+     *    to support sequential Next() calls from the algebra engine.
+     *
+     * 3. Prefetching & Buffering:
+     *    Abstracts the 'paging' logic of the backend. For remote backends
+     *    like etcd, it manages local buffers to hide latency from the executor.
+     *    Think of a driver for an operating system.
+     *
+     * 4. Boundary Enforcement:
+     *    Ensures scans do not cross commit boundaries or logical branch
+     *    definitions unless explicitly requested by the plan.
