Cursor AgentandDaniel 6db0d2b527 Add the V5_NG wheel workflow and detect x86 ISA with CPUID ...

cibuildwheel builds manylinux2014 wheels for CPython 3.9-3.13 plus an
sdist. PyPI and the GitHub Release run only when a v5* tag is pushed.

__builtin_cpu_supports leaves FMA unset when CPython dlopens this
hidden-visibility library on the manylinux2014 libgcc, so dispatch fell
back to scalar. CPUID and XCR0 report the same feature bits.
