- Implemented a new chat endpoint that utilizes Groq for chat completions based on news articles.
- Added a summarize endpoint that fetches news articles from the database and generates summaries using Groq.
- Introduced a new package "@vueuse/core" for improved reactivity.
- Created a comprehensive command UI component with various subcomponents for better user interaction.
