refactor!: rewrite it in rust

[scarf005]

Warning

This PR is a proof-of-concept, heavily WIP, and is not the consensus of BN core dev team and/or contributors.

Purpose of change

Sorry for the shill; also this is obligatory.

currently the codebase has its core engine logic, hardcoded behavior and util functions amalgamated together. using rust FFI gives us the improved toolings of rust, such as

Easy dependency management

A wealth of safe and ergonomic libraries are a keyboard's type away (e.g crate add <package>)

Testing

rust's built-in test module makes it easy to write tests.

Describe the solution

1. setup a simple rust interop using cmake, cxx
2. extract and rewrite utility modules into rust modules.

TODO: add docs on how it works and migration guide

Describe alternatives you've considered

getting stuck in legacy code purgatory

Testing

the program doesn't segfault.

TODO

• migration
  • url_utility.h
  • name.h
  • language.h
• docs
• setup CI/CD
• merge build systems into cmake

Additional context

• a lot of help from reading Rewrite it in Rust fish-shell/fish-shell#9512
• this PR is in no way complete, and will likely be draft for a long time, e.g 6 months.
• As mentioned earlier, it currently serves no purpose other than POC.
• This approach only works on CMake, thus CMake migration must be done first to support other platforms such as windows/mac/android.
