getHighestSnapshotSlot

Returns the highest slot information that the node has snapshots for. This includes both the full snapshot slot and the incremental snapshot slot if available. Snapshots are used for fast validator bootstrap and ledger recovery. This method is useful for operators monitoring node state and for tools that need to determine the node's snapshot freshness.

Parameters
