[FEATURE] Add quick navigation anchors for user messages in chat history

Problem Statement

When having lengthy conversations with multiple questions and topics, it becomes
difficult to quickly locate previous user messages in the chat history. Users
need to scroll extensively through the conversation to find their specific
questions, especially when the AI provides detailed responses that span multiple
screens.

This creates friction in the user experience, particularly for:

• Long troubleshooting sessions with multiple sub-questions
• Reviewing what was previously asked
• Jumping back to specific points in the conversation

Proposed Solution

Add visual markers or navigation anchors for user messages to enable quick
location and scrolling. Possible implementations:

1. Sidebar/Outline View: A collapsible sidebar showing a list of user

messages (first ~50 chars) that can be clicked to jump to that point

1. Breadcrumb Navigation: Add "Previous/Next User Message" buttons in the

chat interface to quickly skip between user questions

1. Visual Markers: Add distinct visual indicators (icons, background color,

or line markers) in the scrollbar showing where user messages are located

Any combination of these would significantly improve navigation in long
conversations.
