+Add the missing operator~ to fmt's software uint128 fallback.
+
+On targets without a native __int128 (e.g. i386), fmt uses its own uint128
+class instead of __uint128_t. format_hexfloat() does `f.f &= ~(inc - 1);`,
+but the fallback class never defines operator~, so the build fails with
+"no match for 'operator~' (operand type is 'fmt::v12::detail::uint128')".
