init_run_context_2d Subroutine

public subroutine init_run_context_2d(ctx, cfg, status, message)

Bring a 2D run context to ready-to-step state.

This is the setup block of the pre-P1 run_euler_2d, moved verbatim (same call order, same log lines): logger + banner + config-loaded line, state init, scheme binding, decomposition, local mesh, case/schemes log lines, work arrays, restart-or-IC, time-scheme binding.

Validated 2D configuration.
integer, intent(out) :: status
