HDF5 2.0 native complex as a first-class type on read; Python libver=

- Datatype::parse returns Datatype::Complex for class 11 (also inside compounds, arrays and VL types) instead of the {r, i} compound view. - Facade: DType::Complex(Box<DType>); read_complex_f32/f64 accept it. - h5rs dump/ls/diff print native complex as h5dump/h5ls/h5diff 2.2.0 do (checked against a fixture written by h5py 3.16 / libhdf5 2.0.0); dump --json keeps the {r, i} compound (hdf5-json has no complex class). - clawhdf5-wasm reads native complex datasets as [re, im] pairs. - Python: clawhdf5.File(path, 'w', libver=...) with h5py's values, mapped to FileBuilder::libver_bounds; 'v108' output opens in HDF5 1.8.23. - Docs: known-issues entry moved to Fixed (history), CHANGELOG, READMEs.
