Syntax errors incorrectly reported in definition files (`*.d.luau`) + types not defined when directory containing multiple projects is opened

[deviaze]

Usually Luau definition files get ignored for syntax errors since they don't follow regular Luau syntax... But when you open a directory that contains multiple projects, and each project has its own definition file/vscode settings/.luaurc, Luau Language Server doesn't realize it has to ignore definition files in those projects.

Types from those definitions files aren't loaded at all for files within those projects, thereby causing a bunch more incorrect TypeErrors.

Directory structure:

scripts
  | fixkcolor
  | | .seal
  | | | typedefs
  | | | | globals.d.luau
  | otherproject
  | | .seal
  | | | typedefs
  | | | | globals.d.luau

If I open scripts/fixkcolor where and cwd is inside the fixkcolor directory everything works perfectly (since the definitions file is linked properly in fixkcolor/.vscode/settings.json), but if I open its parent directory it all goes haywire.

scripts doesn't have a .vscode folder or any definition files of its own since it just stores other projects

Additionally, Luau Language Server doesn't recognize any types from those definitions files within those directories:

Oh, I did not realise when you originally reported this issue that the type definition files are not loaded into the type checker (as they are not part of settings).

This is pretty hard to fix then, especially given there is no official determination that a file is a "definitions file"
