Module solver 

Softness / make_soft and the step context from solver.h. Integration and the serial solve driver live in submodules.

The C b3StepContext carries multithreading scratch. The single-threaded port keeps only the step parameters here; solver scratch is owned locally by the solve pass and world data is passed as separate arguments.
