How is see-and-avoid handled with unmanned weather balloons? Are they
only released in restricted airspace? Seems to me that there are some
parallels with UAVs.

Aircraft are obliged to give priority to balloons, unmanned or not.
No one has asserted that UAVs have priority over aircraft.

Anyway, balloons don't converge on you from your blind side.
