Neovim plugin compatibility layer

[vkuprin]

Fresh's TypeScript plugin system is a big plus, but there aren't many plugins available. There aren't any important tools like Copilot, ESLint, Prettier.

Fresh could start Neovim headless (nvim --embed) and connect to its plugin ecosystem through msgpack-rpc instead of rewriting everything from scratch. This is how the Neovim and Onivim extensions for VS Code work.

This could be the one thing that makes people want to use it.
