Feat: Add markdown-oxide lsp

[Feel-ix-343]

Add initial support for https://github.com/Feel-ix-343/markdown-oxide

i think you can use single_file_support directly.

[Feel-ix-343]

The language server uses root_dir in the initialization, so right now single_file_support does not work.

I do think that root_dir makes sense as is because this way the context in which the file is opened is sent as the root_dir, which makes sense for vaults with folders. The same root dir will be sent if neovim is called with nvim ., nvim file, and nvim folder/file, which adhears to the vault structure and the LSP completion structure

[glepnir]

if you set the single_file_support the root dir is cwd

[Feel-ix-343]

As many people do track their vaults with git, I think it is best to both resolve .git as root and cwd; I think root_dir is best.

My recent commits have this

[Feel-ix-343]

Awesome; works on my end!

[Feel-ix-343]

Hey @glepnir I don't think the single_file_support is working. There are some issues open on my repo saying that the LS doesn't start unless there is a git repo -- in which case root_dir would be sent. I think single_file_support is supposed to send the root_dir but as of neovim 0.9.5 and nightly, root_dir is not being sent (unless there is a git repo).

I believe the solution for neovim 0.9.5 is to send the cwd(), and for nightly to send the vim.uv.cwd()

Shall I open a new PR?

[glepnir]

emm sure. but i may take a look code of there .forget some code on how neovim initialize client when root is emtpy. :p . most work on neovim core rencently ..
