chore(release): roll up v0.3.0 — expensive-eval, gradient-free, multi-fidelity

Browse Source 
CHANGELOG entry for the v0.3.0 cohort, version bump in Cargo.toml and
README. Theme: filling heuropt's expensive-evaluation and constraint-
handling gaps.

Algorithms (9 new): OnePlusOneEs, NelderMead, IpopCmaEs, BayesianOpt,
SeparableNes, Tpe, Hyperband.

Operators (1 new): LevyMutation. Repair operators (1 trait + 2 impls):
Repair<D> with ClampToBounds and ProjectToSimplex.

Selection helpers (1 new): stochastic_ranking_select.

Internal helpers: Cholesky factorization (used by BO).

API additions:
- CmaEsConfig.initial_mean: Option<Vec<f64>> (None preserves existing
  midpoint-of-bounds behavior; used by IpopCmaEs to inject restart
  diversity).
- New PartialProblem trait — multi-fidelity contract used by
  Hyperband.

No breaking changes to v0.2.0 public API.
