Migrate2pyproject.toml

[psolmor]

Migrate packaging metadata to pyproject.toml and define optional extras for test and documentation workflows. This updates the repository to use modern Python packaging, removes the need for ad hoc dependency installation in CI and docs, and keeps the public setup instructions aligned with the project metadata.

The documentation and GitHub Actions workflow have been updated to install dependencies via extras instead of manually listing them. The changelog now includes an Unreleased entry describing the packaging migration.

The installation has been verified in a clean environment, and functionality was checked by running the existing smoke tests (python tests/smoke_notebooks.py).

Installation options:

• Core package:
  pip install .
• With test dependencies:
  pip install .[test]
• With documentation dependencies:
  pip install .[docs]
