feat(scheduler-sim-decision-trace): hook the allocator runner

Browse source 
Task 3.4: the runner records no-plan reasons, the cluster-wide check,
plans (tried, discarded, not tried) and their ends, positions, claimed
skips and per-host candidate verdicts, rollbacks, commit or finalize
failure, and search end. A declined or generator-failed requirement now
counts once as 'no plan generated'. Runner results are unchanged.
