Contributions summary:Stefan primarily contributed to improving the environment variable handling and unit tests within the Neovim project. This involved refactoring code to move environment variable functions to `src/os/env.c`, removing direct calls to `getenv()` and `setenv()` outside that file, and adding unit tests. The changes demonstrate a focus on cleaning up existing code, improving code structure, and ensuring the reliability of environment variable functionalities within Neovim.
