Export.{Snapshot,LeaseCheck,DeviceInfo}, ExportHost.{Reconcile,FinishImport},
ImportHost.Start, and all 11 exportLedger methods carried ctx params that
implementations never consumed (linux FinishImport now reaches into h.runCtx
internally). UrbTransaction.{Wait,Cancel} did consume ctx, but every call site
passed context.Background(), forcing the reverse pattern in endpoint_darwin
where e.ctx was already cancelled. Cancel becomes synchronous, Wait reads
under the close(t.done) happens-before. ExportHost's runCtx now derives in
newPlatformExportHost so Start() is just precondition-check (linux
ensureKernelPath / darwin no-op), and the three pre-Start nil defences in
Close/Events fall out.
