v0.1.0-beta.29

• Resets expanded candidates to the top whenever the panel reopens.
• Clears the input that triggered a dictionary download as soon as the newly installed dictionary is loaded.
• Stages Copy and Cut results behind the text-edit panel so returning to the keyboard no longer flashes or rewrites the result bar.
• Rejects incompatible variant readings and malformed upstream rows when rebuilding downloadable dictionaries.
• Centers Chinese 26-key symbol hints, comma, and period by their visible glyphs.
