[Feature Request] Add keyboard shortcut to copy response to clipboard

Bug Description

Claude Code - Feature Request: Copy Response to Clipboard

Problem

When using Claude Code in a terminal (e.g., Warp), copying AI responses by selecting terminal text introduces extra newlines at visual line-wrap points, breaking the formatting when pasting into editors.

Other AI CLIs (e.g., Atlassian's RovoDev CLI) solve this with a "Copy to clipboard" option (triggered by a single keypress) that copies the raw response text directly - preserving markdown and correct line structure, bypassing terminal rendering artifacts entirely.

Request

Add a keyboard shortcut (e.g., c after a response, or similar) that copies the last response as raw text to the system clipboard. Optionally, a second option like "Copy with tool calls" would also be useful for debugging sessions.

This would significantly improve the workflow for users who write, export, or paste Claude responses into external editors.
