This adds cp314t to the build matrix so free-threaded CPython 3.14 wheels are published. The bindings were already declared GIL safe in #2063, and cibuildwheel 4 builds free-threaded wheels by default; the matrix just never selects them.
The two linux 32 bit combos are excluded because numpy (used by the tests) ships no i686 free-threaded wheels.
Context: conda-forge only enables free-threaded builds for packages with cp314t wheels on PyPI, and highspy is one of the last blockers for a free-threaded cvxpy (conda-forge/cvxpy-feedstock#124).
