chore: ruff auto-fix C401, C416, C408, PLR1722 (#23940)

C401:   set(x for x in y) -> {x for x in y}      (set comprehension)
C416:   [(k,v) for k,v in d] -> list(d.items())  (unnecessary listcomp)
C408:   tuple()/dict() -> ()/{}                   (unnecessary collection call)
PLR1722: exit() -> sys.exit()                     (adds import sys where needed)

21 instances fixed, 0 remaining. 19 files, +40/-36.
