Most commonly, on interior walls, this occurs on midwalls (roughly along centerline of house, commonly hall or bathroom walls) which run perpendicular to the attic floor joists or trusses. Drying out and cold shorten the wood in the attic framing, causing the center of the framing to lift up - and the ceiling drywall is attached to the bottom of that framing, so it lifts up off the walls near the centerline of the house, most evidently at perpendicular walls near the centerline of the house. One or more of the responses talks about using high-extension caulk instead of drywall compound to close up the crack.


In new construction/remodels the ceiling drywall (which should sit on TOP of the wall drywall at the edges) can be left unfastened to the ceiling joists/trusses for a couple of feet from the wall where the crack shows, and be caulked to the wall drywall, so it stays with the wall rather than rising with the trusses/joists at that point.


If the stair hairline crack is quite straight (within 1/8" or so) could be a cracking drywall joint for same reason.


Repair could be done by Handyman if you find one who can do good drywall repaiurs and repainting. If shooting in the dark on his capabilities better to go with a Drywall contractor for the patches, then a Painter if you are not a DIY'er.
