…ycles (#9164) Fixes a chunk-splitting issue where the runtime module could be placed in a chunk that introduced a cyclic dependency between chunks. The optimizer now selects the dominator of all runtime consumers for placement, ensuring runtime-containing chunks load before their dependents. Includes a regression test for issue #8920 and updates to the code-splitting design doc. closes #9161 closes #9224
