Replace Babashka with FFI/Sidecar library

[atomicptr]

This is an experiment to replace Babashka with a Sidecar library in Rust (and a new CLI tool called bridge)

I initially implemented stuff in Babashka because you can't do a lot of stuff in Neovims lua and this seemed like a great idea, however this kinda got me into implementing most logic in Clojure because I wanted to limit how much calling between both worlds we do with the custom RPC stuff.

This however has some disadvantages, one is in order to ship this with only Babashka I can't use dependencies (which makes #35 for instance kinda difficult) because while Babashka ships with a ton if you need anything else the user has to have a JDK available which I don't like.

Things to port

• send command
• list commands
• set default editor (modifying Defolds config)
• launch neovim / neovide
• focus handler for neovim & game
• installing & managing neovide (if necessary)
• installing & managing mobdap
• installing & managing dependencies
• dependency .scrip_api -> lua compiler

Other tasks

• Fix Add ability to switch between file sockets and network sockets via config #27
• Fix Remove Defold Lua annotations from the repository #44
• Fix New dependencies don't get automatically added to LSP while Neovim is running #39
• clean up old dependency installations
• get rid of the intermediate lua -> bridge json file thing (if possible)
• add sidecar builds to pipeline
• handle sidecar installation
• testing on linux
• testing on windows
• support macos auto-neovide installations
• testing on macos
