/// Seed the BFS queue with direct deps from every importer manifest.
///
/// When a package is declared in more than one section
/// (`dependencies` + `devDependencies`, etc.) we keep only the
/// highest-priority entry — `dependencies` > `devDependencies` >
/// `optionalDependencies` — matching pnpm, which silently drops
/// the lower-priority duplicates on resolve. Without this the
/// same name gets pushed into the importer's `DirectDep` list
/// twice (once per section), and the linker's parallel step 2
/// races to create the same `node_modules/<name>` symlink from
/// two tasks, producing an `EEXIST` on the loser.
