NLopt is double-only, so float forces the in-house SQP (guarded so you can't mix them). sqp.hpp + callbacks ported to real, precision-aware tolerances (old 1e-9 consts were below float eps). Tests green both ways. Benches: float wins the SIMD kernels ~3x, not the solve — that's scalar solver linear algebra.

add float support. We have always had float support for blast::real, but NLopt only took doubles. Now, if we use Blast's SQP solver, we can use floats.
Surprisingly, it is not faster at all. Maybe even a little slower. I will investigate further, but for now at least the support is there.
