pub fn enumerate_gruel_files(root: &Path) -> Vec<PathBuf>Expand description
Enumerate every *.gruel file under root, respecting .gitignore
and skipping .git/target.
Used to populate the candidate path list that @import resolution searches
against — NOT to build a compilation unit. The LSP analyzes each open file
as its own root and only pulls in files reachable through its @import
graph.
