feat(keywords, ui): add suggestion module and UI for context switching

Added new `add_suggestion` module to support suggestion handling logic.
Updated `index.html` to include a dynamic suggestions container that fetches and displays context suggestions.
This improves user experience by enabling quick context changes through interactive suggestion buttons.
