Summary by cubic

Adds message queuing to the CLI chat: pressing Enter during streaming now queues your message and sends it automatically when the model finishes. This improves flow so you can keep typing. Addresses Linear CON-3768.

• New Features
  • Introduced a FIFO MessageQueue with timestamps and debug logs; supports optional image attachments.
  • UserInput now enqueues submissions during streaming instead of blocking Enter; input is cleared immediately.
  • useChat processes one queued message after each response (with a brief delay to let UI update) and updates input history when processed.

EDIT: this is now resolved

There is a current problem with the implementation. Any help would be appreciated.

Currently when the message is dequeued and added to chat history, the chat history/gui does not show the sent message. Here is a video to understand to show the problem.
