Add missing <algorithm> header to jit_compiler.cpp

Fixes compilation error on Linux where std::find_if is used on line 121
but the <algorithm> header was not included. While this might work on
some platforms due to transitive includes, it's not guaranteed by the
C++ standard.

Resolves issue #2459
