[Feature]: Support Claude Code /ide integration (like VSCode/Cursor)

[kiki830621]

Feature description

Claude Code CLI has an /ide command that connects to IDEs like VSCode and Cursor, enabling:

• Real-time file change tracking
• Automatic diff display when files are modified
• Seamless navigation between terminal and editor

Currently, running /ide in Claude Code inside Wave Terminal shows no connection because Wave Terminal isn't recognized as a supported IDE.

As a user, I would like Wave Terminal to support Claude Code's /ide integration, so that:

1. /ide command recognizes and connects to Wave Terminal
2. File modifications from Claude Code are reflected in Wave's editor/preview widgets
3. Users get the same AI-assisted coding experience as in VSCode/Cursor

Implementation Suggestion

This would likely require:

• Implementing the protocol/API that Claude Code uses to communicate with IDEs
• Exposing Wave Terminal's editor and file preview widgets to external tools
• May need coordination with Anthropic's Claude Code team on their IDE integration spec

Reference: https://docs.anthropic.com/en/docs/claude-code (Claude Code documentation)

Anything else?

Wave Terminal already has built-in editor and file preview features - this integration would leverage those existing capabilities to compete with VSCode/Cursor in the AI coding space.
