Typing Indicators

[cfcosta]

Currently, when the user sends a message, the LLM does a request, and sends back the fully-formed message to the user. Instead, it should be more interactive, clearly indicating t
o the user that generation is happening.

There's a possible option, which is using the live message kind, where it is updated on the fly as generation happens.

• Investigate if it is possible to use live messages.
• If not, implement normal typing indicators.
