Feature Request: One-command installation between CLI and Desktop app

Feature Request

Add seamless cross-installation capabilities between the Claude CLI and Desktop app.

Proposed Commands

From CLI:

claude install desktop
# or
claude desktop install

From Desktop App:

• Menu option or command to install/setup the CLI
• Perhaps: Settings → Install CLI tool

Use Case

When troubleshooting or switching between the CLI and Desktop app, there's currently no integration between the two tools despite being part of the same Claude ecosystem. This creates friction in scenarios like:

• User encounters issue with desktop app and needs to reinstall from CLI
• Developer wants to install desktop app but is already using CLI
• Users want both tools but don't realize they need separate installation steps

Current State

• Desktop app and CLI are completely separate installations
• No awareness or integration between the two
• Users must manually find and download each separately

Expected Benefit

• Streamlined user experience
• Easier adoption of both tools
• Better integration within the Claude ecosystem
• Reduces friction when troubleshooting issues

Related Issue

This became apparent when trying to resolve #20136 - when the desktop app failed, there was no way to easily reinstall it from the CLI.
