perf: enable -ffp-contract=fast on GCC and /fp:contract on MSVC

Aligns GCC and MSVC FP semantics with clang's default (-ffp-contract=fast). All three compilers now use FMA contraction, producing consistent FP results across the full compiler matrix. Clang already had this by default; this makes it explicit for clang and enables it for GCC/MSVC. Unblocks arithmetic loop fusion optimizations (P6/P7/P8) that were blocked by cross-compiler FMA divergence.
