This uses `PyObject_GetOptionalAttr` which is backported in capi
compat.  This function significantly speeds up many attribute
lookups and thus dispatching protocols.

Scipy openblas 0.3.27.44.4

We had logic in place to drop (most) metadata, but the change
had a small bug: During saving, we were still using the one with
metadata...

Maybe doesn't quite close it, but big enough of an improvement
for now, I think, so

Closes numpygh-14142

ENH: Use ``PyObject_GetOptionalAttr``

BUG: Do not accidentally store dtype metadata in ``np.save``

When many bins are requested in a small value region,
it may not be possible to create enough distinct bin
edges due to limited numeric precision. Up to now,
`histogram` then returned identical subsequent bin
edges, which would mean a bin width of 0. These bins
could also have counts associated with them.

Instead of returning such unlogical bin distributions,
this PR raises a value error if the calculated bins
do not all have a finite size.

Closes numpy#27142.

BLD: use smaller scipy-openblas builds

These were skipped due to failing, but they are passing again now.

Closes numpygh-26824

CI: Re-enable nightly OpenBLAS test runs

TYP: add td64 overload for `mean`

MAINT: use npy_argparse for einsum

This is based on what Matti wrote in numpygh-27105 but also adding it
to the migration guide.

Closes numpygh-27083

This commit performs the following changes:

1. cibuildwheel version 2.20.0 is added for building
and testing the Pyodide wheels for NumPy in its workflow
for out-of-tree builds.
2. The workflow sets the CIBW_PLATFORM environment
variable in order to point to Pyodide as the build target.
3. The version of Pyodide used is bumped to the recent
version 0.26.1.
4. The TOML tables are updated to use cibuildwheel's
provided overrides for the test command, the wheels'
repair command, and the setup arguments needed at the
time of building the wheel.
