Here is the patch to upgrade all dependencies to the latest version and changed the language version to 2021

Hi, this is an interesting project. I have upgraded all dependent libraries to the latest version and changed the Rust edition to 2021. Here is the patch file for changes and it will be compiled without any error or warning. But I am not sure they are all correct. Crate nix has many break changes.

[update_dependencies_crate.patch](https://github.com/user-attachments/files/16318026/update_dependencies_crate.patch)

Review update_dependencies_crate.patch against the repository and inspect the dependency and Rust edition changes, especially the nix breaking changes. Run the project's existing build and tests; done means the upgrade is accepted with Rust 2021 and dependencies working without errors or warnings.
