/**
 * Safe accessors for NotebookEntry metadata.
 *
 * Notebook entries loaded from disk may be missing array fields when written by
 * older versions or by hand. Direct `.join()` / `.map()` on undefined crashed
 * `buildAskQuestionDescription` (issue #33). These helpers always return a
 * defined string, so callers never need to null-check.
