- Bump Cargo.toml + pyproject.toml from 2.0.0-alpha.1 to 2.0.0. - Restore PyPI distribution name to 'optimizr' (continuity with v1.4.x). Rust crate stays 'optimiz-rs'; both expose Python module 'optimizr'. - README: new 'What's New in v2.0.0' section listing every advertised primitive (solve_volterra, solve_fractional_ode, linear_bsde_constant_coeffs, mean_reverting_mckean_vlasov, historical_var_py, etc.) with corrected install command 'pip install optimizr'. - tests/test_v2_api.py: 20-test non-regression suite with analytic ground-truth checks for every v2 primitive plus a parametrised guard over the v1.x public surface. - CHANGELOG: 2.0.0 entry documenting the release. Build verification: - maturin develop --release --features python-bindings -> optimizr-2.0.0 wheel built - pytest tests/test_v2_api.py: 20 passed, 0 failed - cargo test --lib --no-default-features: 124 passed; 5 pre-existing failures (mrsjd, ou_estimator, hurst_random_walk, hjb_solver_symmetry, regime_switching) unchanged since v1.1.
