Phase 0.3 of the mutation-testing campaign. Extends the inline tests in
src/explorer/mod.rs with 24 new tests covering the gaps cargo-mutants
identified — about 30 surviving mutants in this one file.
Coverage added:
- Exact-output tests for ToDecisionValues impls on Vec<f64>, Vec<i64>,
Vec<bool>, Vec<usize> (the previous tests only asserted lengths or
spot-checked individual entries).
- from_result propagates evaluations / generations from the
OptimizationResult into RunMeta.
- with_problem_name / with_wall_clock / with_timestamp each set their
field and preserve the rest of the export.
- to_json emits a JSON containing schema_version, candidates, problem
name, and algorithm name strings.
- to_writer and to_file round-trip the same bytes.
- Free top-level to_json / to_writer / to_file convenience functions
exercised end-to-end (round-trip through tmp file).
- pad_decision_schema at all three boundaries (< target / == target /
> target) to pin the < comparison.
- candidate_to_export's in_pareto_front toggles at front_rank == 0.
- candidate_to_export's feasible toggles at constraint_violation <= 0.
- candidate_to_export pads short objective vectors and truncates long
ones (the defensive branch).
