Migrate to pyproject.toml and bump version to 2026.1.1

Replace legacy setup.py with a PEP 621-compliant pyproject.toml to
support Python 3.12+ build environments where setuptools is no longer
automatically available.

- Add pyproject.toml with setuptools.build_meta backend and full
  project metadata
- Remove setup.py
- Bump __version__ in __init__.py to 2026.1.1 to match pyproject.toml
- Add Python 3.10, 3.11, and 3.12 classifiers
