[FEATURE] Native VSCode extension: in-session text search (Ctrl+F) within the current conversation

What feature would you like?

A simple in-panel find (Ctrl+F) in the native VSCode extension that searches the text of the current conversation, highlights matches, and lets you jump between them (next/previous).

Current behavior

• The native VSCode extension has no way to search the text of the ongoing conversation. The "Session history" button searches across/between sessions, not within the current conversation's message content.
• The terminal CLI has this in fullscreen rendering mode (Ctrl+O transcript mode, then / to search, n/N to jump between matches — see https://code.claude.com/docs/en/fullscreen.md), but the native extension does not.

Prior reports (all closed / stale / locked)

This has been raised before but every prior issue is closed and locked, so there is currently no open tracking issue:

• #48535 (closed as duplicate of #37182)
• #37182 (closed, stale)
• #30599 (closed, stale)

Filing a fresh, focused request since none of the above is open.

Request

Add a native in-panel Ctrl+F that searches the current session's messages (both user and assistant text), with match highlighting and next/previous navigation.

Use case

Quickly locating something said earlier in a long conversation without leaving the extension or exporting the transcript.

Environment

• Claude Code v2.1.167, native VSCode extension on Windows 11.
