Downloading the documentation artifact and opening with python -m http.server --directory /dir/with/unzipped/docs, the changes seem to be working, and there are docs pages for mkl_random.interfaces, the patching, and new APIs

PR is ready for review

Thanks for writing these up! The interfaces and patching pages are a really useful addition, and I checked that every function in the autodoc lists is actually exported by numpy_random. It has fallen pretty far behind master, though, so it needs a rebase before it can merge; details inline.

• This one needs a rebase before it can merge: it's 171 commits behind master and conflicts in how_to.rst, where master has since added a thread-safety section. The red 3.14t Jenkins builds look like a side effect of the old base too, since it predates the free-threading support from #159, so a rebase should clear those.

#165 also reworks api.rst (autosummary tables plus numpydoc) and removes the # no-cython-lint markers that this hook strips, and both PRs touch the same mklrand.pyx docstrings. Would it make sense to land #165 first and rebase this on top, keeping the new interfaces and patching pages and dropping the overlapping api.rst/conf.py changes?

[jharlow-intel]

Could we also cover the command-line patching here? On master, python -m mkl_random --patch install|uninstall|status manages a persistent patch, and python -m mkl_random --with-numpy-patch <command> runs a single command with the patch applied; neither is mentioned yet. A short section, or a follow-up issue, would round this out.

Nit: mkl.MKLRandomState here should be mkl_random.MKLRandomState (the old mkl.RandomState typo carried over in the rename).

Suggested change

	The basic random number generator is chosen by specifying :code:`brng` keyword argument to the constructor of :code:`mkl.MKLRandomState` class.
