With the help of @lhames, This pull request introduces the `dlupdate` function in the ORC runtime. `dlupdate` enables incremental execution of new initializers introduced in the REPL environment. Unlike traditional `dlopen`, which manages initializers, code mapping, and library reference counts, `dlupdate` focuses exclusively on running new initializers.
