pub fn find_package_roots(project_root: &Path) -> Vec<(Language, PathBuf)>Expand description
Find all LSP workspace roots within a project for monorepo support.
Recursively walks the entire project tree (respecting .gitignore) to find
all manifest files. Each manifest’s parent directory becomes a workspace
candidate. De-nests: if a parent directory already has the same language
marker, child directories are skipped (e.g., Rust workspace crates don’t
each get their own LSP root — the workspace root covers them).
Returns (Language, PathBuf) pairs sorted by path depth (shallowest first).
