howdy test crashes with NumPy 2.x due to scalar indexing

Description

sudo howdy test crashes on systems using NumPy 2.x.

Error:

IndexError: invalid index to scalar variable.

The issue happens in cli/test.py:

hist_total = int(sum(hist)[0]) value_perc = float(value[0]) / hist_total * 100

NumPy 2.x returns scalar values here instead of indexable arrays.

Environment:

• CachyOS
• howdy-git r592.d3ab993
• Python ...
• NumPy 2.5.2
