Control how language server interacts with workspace

[jtlandis]

Hello, I am fairly new to using LSP, but I'm trying to get to the bottom of a bug when using the languageserver and lintr packages within the zed editor: ocsmit/zed-r#6

As I understand it, zed is sending all open files to the languageserver which is causing lintr to be run on the file. I know that .lintr files can be used to list directories (or specific files) that lintr shouldn't be run, but is there a way to specify the converse, i.e. which files lintr should only be run on?

I wasn't really sure if this is something that is done via the languageserver options, the lintr package, or just zed itself.
