NestPipeline.Run now bundles parts that fit other parts' enclosed cutouts
into their frames before the selected engine, for desktop, Console, MCP and
API alike. A valid complete bundled trial is kept; a refused trial falls back
to the ordinary solve (reason on RefusedCutoutTrial), and an incomplete trial
is compared with it, keeping whichever valid proposal places more. An
incomplete but valid trial is now keepable like any incomplete result.
Expanded sheets list each frame's inserts before the frame, so the committed
order cuts every insert before the cutout that releases its slug.
