GCC 13 produces the following true positive warnings:
- `-Wredundant-move` when trying to move `result->tooltip()`, which
is a const reference in `Assistant/main.cpp`
- `-Wuse-after-free` when freeing an environment variable before
removing it from `s_malloced_environment_variables`
- `-Wdangling-pointer` when storing an AST node's `this` pointer to the
interpreter's node stack in LibJS. This is not actually an issue, as
it is popped when the scope ends, but GCC has no way of telling this.
