🌿 feat: Multi-response Streaming

[danny-avila]

Summary

Closes #3028

Adds ability to message two different endpoints/models/presets at once.

You can use the "+" text command to add a second response setting, or simply click on the "+" button now found in the Header.

You can select which response to reply to, allowing you to navigate the conversation with the preferred response

• Messages also now describe their depth when rendered
• added dev mode browser console logger (minimal implementation)
• optimized rendering for user message icons
• fixed an issue where regenerations/edits in a new chat with an image attached would not recognize the image
• Updated footer to use the new slogan
• remove info level of logs in favor of debug level for GoogleClient
• fixed an issue discovered with aborting message requests
