Replace jupyter_packaging + setuptools with hatchling + hatch-jupyter-builder for a modern build pipeline. Update CI to use current toolchain versions. - Replace setup.py/setup.cfg/MANIFEST.in/pytest.ini with pyproject.toml - Use hatch-nodejs-version to derive version from js/package.json - Use importlib.metadata in _version.py - Bump @jupyterlab/builder from ^3 to ^4 - Regenerate yarn.lock - Update CI: actions/checkout@v4, setup-miniconda@v3, Python 3.10, Node.js 18, JupyterLab 4 - Add pytest step to CI workflow
Covers: large trees, icon styles, dynamic operations, selection events, deep nesting, property toggles, positional insert, single selection, and scale testing.

The current CI is broken because
yarn installfails under the outdated toolchain (Node.js 14, Python 3.8,jupyter_packaging ~0.7.0). Rather than patching the old setup, this PR modernizes the entire build system to align with the current Jupyter ecosystem.
