Fix GCC 16 LTO build failure with multi-target dispatch

Remove always_inline from STDSortComparator. This function is passed
to std::sort, and GCC 16 rejects forced inlining when the caller and
callee have mismatched target attributes during LTO.

This occurs when the library is used via the header-only static include
with multiple dispatch targets (e.g. AVX-512 and baseline) linked
together, as NumPy does.

Standalone builds are unaffected since they use -march=skylake-avx512
for the entire translation unit.
