This pull request introduces a comprehensive redesign of gomi's trash management system, providing a more robust, flexible, and standards-compliant approach to file deletion and restoration.

ref #59

What

• Implemented a new multi-strategy trash management architecture
• Added full support for XDG trash specification

Why

The new architecture addresses several key challenges in CLI trash management:

1. Standards Compliance: Full adherence to the XDG trash specification ensures compatibility with modern desktop environments.
2. Flexibility: Users can choose between XDG, legacy, and auto trash strategies.
3. Reliability: Improved error handling and support for different storage backends.
4. Performance: More efficient file tracking and restoration processes.
