Subject: [PATCH 1/2] ci: build and test aarch64 manylinux wheels on
 ubuntu-24.04-arm runners

nlopt ships no aarch64 wheels on PyPI, forcing source builds (or making
installs impossible) on ARM hosts like NVIDIA DGX Spark, Jetson Thor and
GH200. GitHub now provides free ubuntu-24.04-arm runners for public repos,
so add them to the cibuildwheel matrix (manylinux_2_28_aarch64 image) and
to the wheel test matrix. The existing test-step file discovery already
matches (runner.os=Linux -> 'lin', chunk=ubuntu-24.04-arm).

Subject: [PATCH 2/2] ci: bump x86_64 manylinux image to 2_28 (numpy>=2.5 needs
 gcc>=10.3)

numpy stopped publishing manylinux2014 wheels, so pip builds it from
source inside the cibuildwheel container; manylinux2014's gcc 10.2.1
fails numpy's GCC>=10.3 check. manylinux_2_28 ships a modern toolchain
(same image family already used for aarch64).
