Theme: production lifecycle. heuropt becomes deployable for long- running, real-world workloads. No breaking changes — Optimizer trait gains a default-impl run_with method that falls back to run. Adds: - src/observer/ module: Snapshot, Observer trait, ControlFlow, plus built-in MaxTime / MaxIterations / TargetFitness / Stagnation / Periodic / AnyOf / AllOf and a closure impl. - Optimizer::run_with(problem, observer): default-impl on the trait, overridden for full per-gen visibility on Nsga2, RandomSearch, and DifferentialEvolution. Other algorithms inherit a final-only notification — full per-gen support follows incrementally. - New 'tracing' optional feature plus TracingObserver that emits structured debug! events per generation. - src/metrics/igd.rs: IGD + IGD+ performance indicators against a reference set. - src/metrics/r2.rs: R2 indicator using the weighted Tchebycheff utility; pair with das_dennis for the canonical weight set. - examples/constrained.rs: BNH constrained 2-objective problem solved with NSGA-II + observer composition (MaxTime.or(Periodic)). Bumps Cargo.toml to 0.6.0; CHANGELOG entry consolidates the above. Existing 247 unit + 38 doctest + 32 algorithm-property + property / metric / numerical-stability tests all pass; bit-identical compare output verified post-DE refactor.
