Struct ShowCommandController 

pub struct ShowCommandController { /* private fields */ }

Presentation layer controller for show command workflow

Displays environment information with state-aware details. This is a read-only command that shows stored data without remote verification.

Responsibilities

• Validate environment name format
• Delegate to application layer for data extraction
• Display state-aware information to the user
• Provide next-step guidance based on current state

Architecture

This controller implements the Presentation Layer pattern, handling user interaction while delegating business logic to the application layer.
