Streaming messageNew

Assistant message that streams in word by word with a soft fade, light markdown (bold, inline code, lists, fenced code), code blocks that hold their frame while code arrives, a Stop button while streaming and Copy / Regenerate when done.

Installation

Set your access key from API keys as NEXTUI_TOKEN in .env.local and add the @nextui namespace below to components.json once. Then every item installs by name. Each install counts as a copy on a free account.
