Detailed Description

Executes one four-stage, operator-split gyrokinetic timestep.

OneStep is the central bridge between ControlAll and the physics subsystems. It sequences coordinate conversion, field interpolation, Runge–Kutta marker and weight updates, inter-domain marker migration, collisions and sources, gyro-density correction, and electromagnetic pullback. Operations are selected per species from SpeciesVariables and use process-wide state created during module initialization.
