[Minor] Add missing <algorithm> include for gcc 14

[Minor] Add missing <algorithm> include for gcc 14

This commit addresses a compilation issue when using GCC 14. According
to GCC 14's porting guide [1], some C++ Standard Library headers no
longer include other headers they used to use internally. Specifically,
<algorithm> must now be explicitly included.
