Follow-up for #1559, targeting its branch.

Problem: under customParallelIterations the run has no run-level data; each partition holds the row its host injected (partition.iterationData). runNestedRequest built the nested run's row from state.data, so in a per-VU-data run a pm.execution.runRequest target sent {{col}} literally and saw an empty pm.iterationData. Found by the AUTO-1178 audit of performance runs (lib @postman/performance-test with #1559 + #1565).

Fix: getParentIterationRow(run) picks the row from the calling partition (rootCursor.partitionIndex) when the run uses custom parallel iterations. The streaming and plain paths are unchanged.

Tests: unit 612 passing here; lint clean. A run-level test needs #1565 as well (a nested run under customParallelIterations hangs without it), so it lives on the #1559 + #1565 merge: test/integration/runner-spec/run-collection-request-parallel.test.js "with per-VU iteration data > should hand the nested request the calling VU's iteration data row", which fails before this change and passes after (runRequest specs 33 passing). The performance-test lib's run-level suite covers it too ({{var}} in the nested request and pm.iterationData in nested scripts, 3 VUs).
