Subject: [PATCH] refactor(utils): include <cstddef>/<type_traits> used by
 as_bytes

The as_bytes overloads use std::byte/std::size_t (<cstddef>) and
std::is_trivially_copyable_v (<type_traits>); after the earlier include trim
these compiled only via transitive <span> includes on the fleet's libstdc++.
Include them directly (include-what-you-use).
