 *
 * Skips `.git`, `node_modules`, `.DS_Store`, common secret-bearing filenames
 * like `.env`, `.npmrc`, and private-key material (plus any names in
 * `opts.ignore`) at every depth. Pass `{ includeSensitive: true }` to opt in
 * to collecting those sensitive filenames deliberately. Rejects symlinks.
 * Throws `LocalError` if the directory does not exist, is not a directory, or
 * contains no deployable files after the ignore list is applied.
