feat(selection): add random and single-objective tournament selection

`select_random` samples `count` decisions with replacement and clones
them out of the population (spec §10.1).

`tournament_select_single_objective` runs binary-or-larger tournaments
with the spec's tiebreak order: feasible beats infeasible, lower
violation among infeasibles, and direction-correct objective comparison
among feasibles. Panics if not exactly one objective (spec §10.2).

Selection helpers stay under `heuropt::selection` and are not part of
the prelude (spec §15).
