Module errors 

Presentation Layer Error Types

This module defines unified error handling for CLI commands following the error handling conventions documented in docs/contributing/error-handling.md.

Design Principles

• Clarity: Unambiguous error messages with specific context
• Traceability: Full error chains preserved for debugging
• Actionability: Clear instructions for resolution
• Unified Structure: Single CommandError enum containing all command-specific errors

Error Hierarchy

CommandError
└── Destroy(DestroyError)       # Destroy command errors
└── Exists(ExistsSubcommandError) # Exists command errors
