pub fn load_project_packs(project_dir: &Path) -> Vec<LibraryPack>Expand description
Scan project_dir/libraries/*.zen and parse each file into a LibraryPack.
A missing libraries/ directory (or a project_dir without one) yields an
empty vector. Files that fail to read or parse are skipped — a note is
written to stderr — so one bad pack never aborts the whole listing.
