…form_neighbor_sample` (#4561)

This PR re-enables the `benchmarks/cugraph/pytest-based/bench_cugraph_uniform_neighbor_sample.py` benchmark in the MNMG nightlies. 

This benchmark was previously being skipped due to the fact that the benchmarks are configured to run with Pytest markers `"managedmem_off and poolallocator_on"`. Thanks to @jameslamb for spotting this inside `conftest.py`

By adding the missing markers to the test (and removing some `dgx` machine specific dask-client configs), the benchmark should properly run in the nightly jobs.

This PR fixes an issue that recently arose due to a change in constructing a `cudf.Series` object.

`test_property_graph_mg.py` uses a function from `utilities/utils.py` to construct a Series object from 2d arrays. The function is now using the correct `cudf.Series._from_column` API.

`scikit-build-core==0.10.0` was released today (https://github.com/scikit-build/scikit-build-core/releases/tag/v0.10.0), and wheel-building configurations across RAPIDS are incompatible with it.

This proposes upgrading to that version and fixing configuration here in a way that:

* is compatible with that new `scikit-build-core` version
* takes advantage of the forward-compatibility mechanism (`minimum-version`) that `scikit-build-core` provides, to reduce the risk of needing to do this again in the future

This PR addresses failures seen in certain PRs (like [here](https://github.com/rapidsai/cugraph/actions/runs/10372270389/job/28718471674?pr=4606#step:7:5269)) due to a [recent change](rapidsai/cudf#16514) to `cudf` that disallows selecting duplicate column labels.

---

In `hypergraph.py`, this PR modifies `_create_hyper_edges` and `_create_direct_edges` to ensure that DataFrames are being indexed by non-duplicate column values.

This is done by taking a list that includes duplicates (`fs`), and removing the non-unique values
```python
fs = list(set(fs))
```


_This part requires some attention from the author of the unit test @jnke2016_

In `test_hypergraph.py`, this PR adds the `check_like=True` arg to `assert_frame_equals` function because the ordering of the columns is different for the two DFs.

This PR copies the source files from cugraph-ops that provide the `get_sampling_index` function into the cugraph source code.  The code was placed in a single source directory (`src/from_cugraph_ops`) and cleaned up a little bit to remove parts of the cugraph-ops infrastructure that were unused.

There are still improvements that could be made, but this should be functional in allowing us to avoid using the version from cugraph-ops.

## Notes for Reviewers

This is part of ongoing work to add Python 3.12 support across RAPIDS.
It temporarily introduces a build/test matrix including Python 3.12, from rapidsai/shared-workflows#213.

A follow-up PR will revert back to pointing at the `branch-24.10` branch of `shared-workflows` once all
RAPIDS repos have added Python 3.12 support.

### This will fail until all dependencies have been updates to Python 3.12

Graph input with duplicate edges intended for `Graph`/`DiGraph` instances resulted in internal PLC `SGGraph` instances with duplicate edges, which were effectively treated as MultiGraphs and caused incorrect results from algorithms like `pagerank`.

This PR sets the `drop_multi_edges` PLC `SGGraph` ctor option to have PLC remove duplicate edges on `SGGraph` creation.

The overhead to drop duplicate edges for non-MultiGraphs is negligible, and in the case of a large test graph (wikipedia data, 37.5M nodes, 464.5M edges) resulted in <s>an overall _speedup_ for pagerank going from 12.2 seconds to 10.7 seconds on my workstation, likely due to fewer edges to process</s> a minor slowdown from 10.5s to 10.7s. _edit: after several re-runs, the pagerank runtime before the change settled to 10.5, and the runtime after the change was typically 10.7._

A test was added that uses pagerank to ensure Graphs vs. MultiGraphs are handled correctly and duplicate edges are dropped as needed.  The results when run without `drop_multi_edges` set:

…workX Graph classes, needed for zero code change graph generators (#4629)

This is an alternative approach to #4558 for enabling GPU-accelerated NetworkX to "just work". It has similarities to #4558. I opted to make separate classes such as `ZeroGraph`, which I think makes for cleaner separation and gives us and users more control.

There are a few lingering TODOs and code comments to tidy up, but I don't think there are any show-stoppers. I have not updated methods (such as `number_of_nodes`) to optimistically try to use GPU if possible, b/c this is not strictly necessary, but we should update these soon.

I have run NetworkX tests with these classes using networkx/networkx#7585 and networkx/networkx#7600. We need the behavior in 7585, and 7600 is only useful for testing.

There are only 3 new failing tests, and 3 tests that hang (I'll run them overnight to see if they finish). Here's a test summary:
```
5548 passed, 24 skipped, 16 xfailed, 25 xpassed
```
Note that 25 tests that were failing now pass. I have not investigated test failures, xfails, or xpasses yet. I would like to add tests too.

We rely heavily on the networkx cache. I think this is preferred.

It is late for me. I will describe and show how and why this works later.

I opted for `zero=` and `ZeroGraph`, because I find them delightful! Renaming is trivial if other terms are preferred.

Closes rapidsai/graph_dl#606 and [another
issue]

## Proposed Changes
In preparation for GA release, this PR adds a landing page for
`nx-cugraph` in the cugraph API documentation site. The new pages can be
viewed by clicking `nx-cugraph` in the navigation bar at the top of the
page.

### New pages
nx-cugraph
 └─ How it works
 └─ Supported Algorithms
 └─ Getting Started
 └─ Benchmarks
 └─ FAQ

## Notes for Reviewers

- In order to build and test these docs, I modified the `build.sh` file
to use `sphinx-autobuild`.

```bash
122
123     cd ${REPODIR}/docs/cugraph-docs
124     #make html
125     sphinx-autobuild source build/html
126 fi
127
```

- For now, I believe the best way to view these changes is to clone the
PR branch, then run `build.sh` in order to host the webserver locally..

We were pulling the wrong packages because the PyTorch version constraint wasn't tight enough.  Hopefully these sorts of issues will be resolved in the `cugraph-gnn` repository going forward, where we can pin a specific pytorch version for testing.

… zero-code change (#4685)

This is for convenience and sets or updates `NETWORKX` environment variables.

Do we like `NX_CUGRAPH` as the env var name? What should we consider a true value: "True" (case-insensitive) or a non-empty value?

This works with the latest dev version of NetworkX. I have not yet tried it with older NetworkX versions.
