Post-release polish: Production/Stable classifier and refreshed abstract (#10)

- Trove classifier bumped from '3 - Alpha' to '5 - Production/Stable'
  to match v1.0.0.
- CITATION.cff abstract no longer reads as 'reference MATLAB only' —
  reflects that a stable Python package (dcebe on PyPI) is now part
  of the artefact alongside the MATLAB code.
