Phase 0.1 of the mutation-testing campaign: a sweep test per algorithm
(33 total) asserting the exact strings returned by AlgorithmInfo::name()
and AlgorithmInfo::full_name() plus the seed propagated through
AlgorithmInfo::seed().
Before: cargo mutants survived dozens of mutants per algorithm replacing
the name/full_name return values with "" or "xyzzy", and the seed
return with None/Some(0)/Some(1). After: every such mutant is caught
by an exact-equality assertion.
NelderMead is deterministic and has no seed override (intentionally);
its test asserts seed() == None to pin the default-trait-impl behavior.
