Implemented a smooth typing algorithm in assets/js/app.js to improve the visual quality of the AI response stream.

Key changes:

  • Decoupled accumulatedContent (network buffer) from displayedContentLength (visual state).
  • Modified processRenderQueue to consume all pending network packets immediately.
  • Implemented an adaptive step-size algorithm in the animation loop to smoothly advance the displayed text towards the accumulated buffer.
  • Ensuring the loop continues until visual synchronization is complete, even if the network stream has finished.
  • Resets display state correctly on new messages.

Decoupled the network reception of text chunks from the DOM rendering loop.
Network chunks are now accumulated immediately into a buffer.
A separate render loop updates the displayed text at a variable rate, creating a smooth typing effect that catches up to the network stream without lag or jank.
Also fixed state management for repeated queries.

P0 Badge Restore removed send/render functions to global scope

This replacement starting at addUserMessage removes the former top-level chat helpers (window.sendMessage, addAssistantMessage, formatContent, and removeTypingIndicator) while their call sites remain in this file (for example, the input handlers still call window.sendMessage() and chat replay still calls addAssistantMessage()). In a normal browser flow, sending a message or loading existing assistant messages now hits missing-function runtime errors and the chat UI cannot complete its core actions.
