Elior Nataf Lackritz d5238f83cd fix(langgraph): don't walk history for a DeltaChannel that was never written ...

A DeltaChannel with no version at the checkpoint was never written, so it
is empty. channels_from_checkpoint still asked the saver for its history,
and with no snapshot to stop at the walk read every ancestor of the thread
on every load. On SQLite that fails outright once a thread has about 32k
checkpoints: stage 2 binds one variable per ancestor. Only channels with a
version are walked now.
