feat(scheduler-sim-decision-trace): wire tracing into the simulation driver

Browse source 
Task 5.3: session hooks around each sim session; trace-only decisions
are handled first and skip verification, recording, echo and
breakpoints; traced decisions are emitted after the echo gate and before
the breakpoint check; reconstructed dispatches get reconstructed
records; unclaimed traces are freed at both decision free sites.
