Move the pure-header utilities shared by app/ and engine/ out of engine/common/ into a new shared/include/oakutil/ layer (define, lerp, decibel, digit, range, crashpadutils, autoscroll, qtutils, filefunctions declarations, and a trimmed xmlutils exposing a CancelAtom-free void* overload). engine/common/ keeps forwarding headers so internal include paths are unchanged; app/ now includes oakutil/* directly. engine/node/project.h gains an explicit NodeGroup forward declaration previously obtained transitively through the old xmlutils.h.
