Remove nvim-treesitter from dependency list

[vhyrro]

This PR serves two purposes:

1. Remove core.maneouvre (an already deprecated module in need of a rewrite)
2. Remove nvim-treesitter from the dependency list

Why?

nvim-treesitter will soon be dropping their ts_utils module in the main branch. To accommodate for this ahead of time, Neorg is removing its reliance on nvim-treesitter as a dependency. Not only this, the main branch of nvim-treesitter will no longer ship the norg parser due to its reliance on C++ as its scanner (something that is fixed in the V3 parser but not yet shipped within Neorg).

The biggest benefit of this change is loading order - since Neorg needs nothing from nvim-treesitter any longer, nvim-treesitter can load naturally and thus hopefully prevent highlighting errors that we've seen so far.

There is a hack in the codebase right now related to MacOS installation (due to old compilers), but it's one that will soon be removed. The norg tree-sitter parser is already published on luarocks in precompiled form for all major operating systems in a way that complements and does not interfere with nvim-treesitter. This rock can be pulled down as a dependency and can immediately work with nvim-treesitter's builtin highlighting module or the rocks-treesitter.nvim module.

Testers Welcome

I encourage anyone to test this PR and report any errors you may encounter. This is marked as a breaking change but will not affect users, only external modules that may rely on ts_utils themselves :)

TODOs

• Remove :Neorg sync-parsers (issue a deprecation warning for users when they try to use it)
• Remove automatic parser pinning logic
• Rename core.integrations.treesitter to core.treesitter (no longer an integration but a component of the core)
• Remove MacOS hacks by using precompiled parser

[vhyrro]

Just one thing left: make luarocks.nvim use the rocks-binaries servers and precompile the parsers so that users needn't compile them on their machines. After that we're good to go! :D

[vhyrro]

Update: this PR in of itself is complete, it seems like our CI on rocks-binaries is having some issues with compiling C++ code properly, and we haven't found a way to fix it yet. Once that happens, this PR can finally be merged! Should make Neorg more stable :)

[Anrock]

@vhyrro is it possible to get this somehow to master without waiting for rocks-binaries CI? If I understand correctly that will lead to local treesitter compiling as the only option, am I right?

I'm kinda stuck without neorg now, since neorg depends on nvim-treesitter and rocks, and nvim-treesitter is horribly broken with rocks for some reason.

[vhyrro]

@Anrock seems like it's related to the actual compilation process itself which super sucks. I'm trying to fix it over here as fast as I can :)

[vhyrro]

btw @Anrock in the meantime you can use the git version of treesitter with :Rocks install rocks-git.nvim and :Rocks install nvim-treesitter/nvim-treesitter. That should at least resolve the treesitter errors.

We're revamping the luarocks-build-treesitter-parser dependency to use tree-sitter build (the new, recommended way of building TS parsers). It will probably be complete in the next day or two.

Does this adresse usecases where rocks-treesitter.nvim is not used and tree-sitter-norg is installed directly through rocks?

Precisely :)

Temporarily on hold as even more nix + luarocks-related problems are fixed :|
