Enum FixedLambdaSolverStage 

pub enum FixedLambdaSolverStage {
    BinomialMultiNewton,
    MultinomialNewton,
    MultinomialFirth,
}

Fixed-lambda solver stage that owns a resumable coefficient checkpoint.

The multinomial fitter has two distinct objectives: the ordinary softmax likelihood and the Firth/Jeffreys separation refit. Recording the stage is therefore part of correctness: a Firth checkpoint must resume the Firth objective rather than being mistaken for an ordinary multinomial start.
