Function topp3_socp_expert_with_info 

pub fn topp3_socp_expert_with_info(
    problem: &Topp3Problem<'_>,
    options: &ClarabelOptions,
) -> Result<ClarabelExpertInfor3rd, CoppError>

Expert TOPP3-SOCP API with Clarabel solution and linear-solver diagnostics.

Use this variant when callers need more than DefaultSolution, because Clarabel stores linear-solver metadata on the solver info object rather than inside the returned solution.

Status acceptance follows ClarabelOptions::is_allow; see that method for the shared status-handling pattern.
