Expand description

Clarabel-specific solver options.

A typed mirror of the tunable, non-feature-gated fields of clarabel::solver::CoreSettings. Every field is Option, None leaves Clarabel’s own default in place, so the defaults quoted below are informational.

The universal threads option maps to Clarabel’s max_threads, which only affects multithreaded KKT solvers. The default qdldl solver is single-threaded.
