Pull request overview

Refactors test word getters to model “may be missing” values (string | undefined) and threads that through generation/UI logic to satisfy TS and avoid runtime crashes on out-of-range access.

Changes:

• Words.getText(i) now returns string | undefined and callers updated accordingly.
• Word generation updated to accept previousWord possibly undefined and guard punctuation/capitalization logic.
• Multiple UI/logic call sites updated to handle missing words safely (nullish checks / fallbacks).
