Bug: TraceStore::start ts off by one, skipping first simulation event

Bug: TraceStore::start ts off by one, skipping first simulation event: a task in LegoFlow-SWE (Harbor dataset). Observed behavior When a simulation is run using the TraceRunner , the first trace event is never processed. The simulation starts at the timestamp of the second event, causing any…

The task

**Observed behavior** When a simulation is run using the `TraceRunner`, the first trace event is never processed. The simulation starts at the timestamp of the *second* event, causing any object creations, deletions, or modifications in the initial event to be silently dropped. This happens regardless of the trace…
