[Feature Request] Multiple IDE Connection Support for Monorepo Workflows

Bug Description
Feature Request: Multiple IDE Connection Support for Monorepo Workflows

Use Case:
Working with monorepos that contain multiple sub-projects (e.g., frontend/ and backend/), each opened in a separate IDE
instance (e.g., two IntelliJ instances). Running Claude Code from the project root while being able to connect to a specific
IDE based on current work context.

Current Behavior:

• /ide only connects when exactly one matching IDE is running
• No way to select which IDE to connect to when multiple instances are available
• Error message: "Found X other running IDE(s). However, their workspace/project directories do not match the current cwd."

Proposed Solution:

1. Allow /ide to accept a parameter for IDE selection, e.g.:

• /ide frontend - connect to IDE with "frontend" in its project path
• /ide 1 or /ide 2 - connect by index from a list of available IDEs

1. Or provide a selection prompt when multiple IDEs are detected:

Multiple IDEs found:
[1] IntelliJ - C:\...\[PROJECT_NAME]\frontend
[2] IntelliJ - C:\...\[PROJECT_NAME]\backend
Select IDE to connect (1-2):

1. Allow switching between connected IDEs during a session with /ide switch

Benefits:

• Enables efficient monorepo development workflows
• Eliminates need for multiple terminal sessions
• Maintains single Claude Code context across full project
