[FEATURE] Inline/hover explanations for terms in Claude's responses (VS Code extension)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When Claude explains code in the chat panel, the response often contains multiple unfamiliar terms, functions, or logic in a single answer.

To understand one term, I have to ask a follow-up question, which pushes the original explanation further up.

Over a few follow-ups I lose track of the original context and have to scroll back and forth repeatedly to piece things together.

This breaks the flow of understanding, especially for junior/learning developers going through unfamiliar codebases.

Proposed Solution

Add an inline or hover-based explanation feature, similar to GitHub Copilot's hover tooltips, e.g., the ability to click or hover on a specific term/function inside Claude's own chat response and get a short, scoped explanation in a popover, without navigating away from or losing the original answer.

Alternative Solutions

An expandable "glossary" section auto-attached to longer explanations, so unfamiliar terms are defined inline without needing a separate follow-up message.
