…compressAndInsertMapPair. At every call site of InsertIntoLeaf, TryRebalanceLeafOnInsert (Tier 2.5 sibling rebalancing), and SplitLeafNode (Tier 3 leaf splitting), the target insertion index 'slot' within the leaf has already been computed by LeafContains or CheckInsertHint. We can pass 'slot' through these functions into DecompressAndInsert* fxns, removing the redundant while (slot < count && out_keys[slot] < new_key) scalar scan PiperOrigin-RevId: 1016190808
