These redundant `std::move()` calls were identified by GCC-14.
In general, copy elision applies to these places, so adding
`std::move()` is not only unnecessary but can actually prevent
the compiler from performing copy elision, as it causes the
return statement to fail to satisfy the requirements for
copy elision optimization.
