FusedMap

Two or more adjacent Map stages fused into a single pipeline unit by the E-2 optimizer.

The E-2 fuseAdjacent rewrite (in :kuilt-warp-planning) collapses a run of consecutive Map stages into one FusedMap so the E-5 runtime can apply them in a single pass. All constituent transforms are monotone — per CALM, adjacent monotone stages commute, so fusion is safe by construction and never changes the convergent result.

opIds holds the original operation names in execution order. opId (from DraftStage) returns opIds.first() as a representative identifier; use opIds for the complete ordered list. The E-3 cost model should iterate opIds to count fused operations.
