* lang/julia: include lsp-julia w/o language server
Use nonrecursive clone to get lsp-julia without bundled
LanguageServer.jl (plus dependencies) and include instructions in the
README on how to install the language server (bundled or otherwise).
* lang/julia: add checks for julia +lsp in doctor
Add two checks, both only for when the +lsp feature is enabled:
- Check if (:tools lsp) is selected
- Check if LanguageServer.jl is installed
* lang/julia: indicate SymbolServer.jl as dependency
It is itself a dependency of LanguageServer.jl, but it's necessary to
add it separately in order to do `using SymbolServer`.
* tools/lsp: add julia language server to list
* lang/julia: add eglot support using eglot-jl
Forcing eglot-jl to not install its own LanguageServer.jl is a bit of a
hack though.
* lang/julia: make timeout increase buffer-local
Suggestion by @benneti to use `setq-local` instead of `setq` to prevent
a timeout increase in non-Julia eglot buffers.
* Fix issues
