Detailed Description

Drives PlasmaChannel1D in time and records what it did.

Assembles [Empty1D, PlasmaChannel1D, Empty1D] into a Sim1D, then advances the chain with Cantera's CVODE backend, error-controlled and variable order. With hydrodynamics on, that reaction sub-step is the "B" half of a Strang split (NUMERICS.md section 4.2) and this file owns the loop: half a hydroStep, a re-seeded CVODE interval, half a hydroStep again. The radial profiles are recorded at a chosen cadence and returned as flat numeric arrays, since no Cantera object crosses the Python boundary.

Sim1D's own damped-Newton solve() is never called here. The Sim1D exists for the state layout it owns: getInitialSoln(), size() and eval().
