+ build(deps): bump actions/upload-artifact from 3 to 4

+ use unique names for artifacts in different jobs, as required by upload-artifact@4

---------
Co-authored-by: Zhang Yunjun <[email protected]>

+ fix the following error by turning on the `merge-multiple` option, as suggested by download-artifact readme

   - Checking dist/artifact-source: ERROR InvalidDistribution: Unknown distribution format: 'artifact-source'

+ Display the structure of downloaded artifact files, to facilitate the debuging in the future, since this part is easy to have issues

+ update deprecated option names in gh-action-pypi-publish

+ README: fix typo

+ .circleci/config.yml: replace mambaforge with miniforge3

+ .github: add release.yml to ignore contributions by bots in release notes

…backend (#87)

+ convert the build system from `numpy.distutils` to `CMake` and `scikit-build-core`, to support the fortran module compilation for python 3.12+.
   - add `CMakeLists.txt` file for the `solid.for` module
   - `pyproject.toml`: switch the build backend from `setuptools` to `scikit-build-core`
   - `setup.py`: switch the build setup from `numpy.distutils` to `skbuild`

+ .circleci/config.yml: update docker image from `ubuntu:bionic` to `cimg/base`, to avoid the spin up environment error: `Error response from daemon: Head "https://registry-1.docker.io/v2/library/ubuntu/manifests/bionic": received unexpected HTTP status: 503 Service Unavailable`

+ point.py: replace np.NaN with np.nan, as `np.NaN` was removed in the NumPy 2.0 release.

+ pyproject.toml: unpin setuptools/numpy versions, as they are not needed anymore

+ tests/requirements.txt: add meson, to support calling f2py for manual compilation

+ README: remove the export SETUPTOOLS_ENABLE_FEATURES commands, as it's not needed anymore.

+ remove the obsolete setup.py, as it's not needed anymore: all functionality are now covered in pyproject.toml and CMakeLists.txt file

+ pyproject.toml: use dynamic readme

---------

Co-authored-by: Scott Staniewicz <[email protected]>

+ `tests.grid/point.py`: add numeric comparisons between the calculated results and the hardcore numpy array

+ `pyproject.toml`: attempt to fix [the `long_description` syntax error](https://github.com/insarlab/PySolid/actions/runs/9626458068/job/26552735067) while uploading to PyPI, without understanding the logic behind.

+ pyproject.toml: for readme, dependencies, optional-dependencies, use static metadata, instead of dynamic ones, to avoid [the following errors](https://github.com/insarlab/PySolid/actions/runs/9625771487/job/26551314687):

```bash
ERROR    HTTPError: 400 Bad Request from https://test.pypi.org/legacy/
         ['readme', 'dependencies', 'optional-dependencies'] is not a valid dynamic field. See https://packaging.python.org/specifications/core-metadata for more information.
```

+ `build-and-publish-to-pypi.yml`: update OS versions
   - ubuntu: from 20.04 to latest
   - macos: from 11 to 13

+ build(deps): bump pypa/cibuildwheel from 2.14.1 to 2.19.1

+ set `MACOSX_DEPLOYMENT_TARGET="13.0"` as the macos-13 runner is using macos 13.0 not 10.13:
https://setapp.com/how-to/full-list-of-all-macos-versions

+ unset `SETUPTOOLS_USE_DISTUTILS=stdlib` as it's not needed anymore
