[Feat Request] Project level configuration

[Eric-Song-Nop]

Motivation

It seems that whenever I restart the Neovim, I need to re-pin the main file, thus I hope that tinymist can have some sort of project level configuration.

Description

tinymist can read some project level configuration file, either typst.toml or other private configuration file, to determine stuffs like main file, root_dir, exclude file, compilation arguments, or other configurations. For now, some editors can handle some of them, but it might be good to be handled by tinymist to make it more corss-editor.

Examples/Questions

not really any good examples for now
