pyproject: Enhance metadata and add Python version classifiers

- Updated `readme` entry to include content type.
- Added `maintainers`, `keywords`, and `classifiers` fields.
- Defined support for Python 3.10 to 3.14 using `requires-python` and
  `classifiers`.
- Added project URLs for homepage, documentation, and source repository.
