## Which issue does this PR close? - Related to #23982 ## Rationale for this change The existing cases measure COUNT over a RANGE frame on round-robin partition keys: Linear mode over 100 and 10000 partitions, plus Sorted-mode over the 10000 partitions. Each batch contains rows for most of the partition set, and every case exercises a single window expression over one frame type. Add Linear-mode shapes that stress the operator's per-partition state differently: - linear, 32768 partitions, sparse: each batch introduces a block of 2048 previously unseen keys (4 rows each) and never revisits them, so the live partition set grows for the whole run while each batch touches only its newest partitions. - linear, 10000 partitions, ROWS frame, round-robin partition layout. - linear, 10000 partitions, two window expressions, round-robin partition layout. ## What changes are included in this PR?
