 * - Excludes `node_modules`, `.git`, `dist`, and hidden dirs.
 * - Non-existent directories are recorded as errors, not thrown.
 * - Readdir failures within the tree are recorded as errors, not thrown.
 * - Deduplicates by resolved absolute path.
 * - Results are sorted by filePath for deterministic output.
