GHSA-mc9m-6fm9-pghc: Zoo Design Studio: Memory-corruption in memory handling of lib-kcl

A race condition in kcl-lib can result in a use-after-free when accessing environments concurrently. During Vec reallocation, the previous buffer containing Box pointers is freed and replaced. A concurrent get_env operation that has already loaded a pointer to the old buffer may subsequently index into freed memory and retrieve a stale or corrupted Pin<Box>.
