fix(events): close run-state race and restore single error toasts

Self-review findings: the bus now re-reads the run-state snapshot in
onSubscribed so an event racing the store's initial read cannot leave a
stale snapshot (the ordering the old layout listener guaranteed), and the
patch hooks pass errorNotice:false so GuardState/page handlers remain the
only error toast, matching the pre-migration behavior.
