scip_add_linear_cons

Adds <code>lhs &lt;= sum(coefs * x[vars]) &lt;= rhs</code>.

Provides an R interface to SCIP (Solving Constraint Integer Programs), a framework for mixed-integer
programming (MIP), mixed-integer nonlinear programming (MINLP), and constraint integer programming
(2025, <doi:10.48550/arXiv.2511.18580>). Supports linear, quadratic, SOS, indicator, and knapsack
constraints with continuous, binary, and integer variables. Includes a one-shot solver interface
and a model-building API for incremental problem construction.
