Copilot Review:
Backend: geoprocess_tools.py

1. Utility Functions for Naming
   New Functions: slugify and ensure_unique_name are added.
   slugify: Converts titles to URL- and filename-friendly slugs.
   ensure_unique_name: Ensures new layers have unique names, optionally using a UUID prefix.
   Purpose: These help create clear, unique, and clean names for output files and layers, avoiding duplicates and weird characters.
2. LLM-Driven Metadata Generation
   Enhanced Prompting: The LLM prompt in geoprocess_executor now asks for:
   A short, descriptive result name (title)
   A brief description of the operation
   JSON output with result_name and result_description
   Parsing LLM Output: The executor now expects and processes these new fields.
3. Operation Details
   Operation Logging: The executor now records the exact steps taken, input layers, and query, returning these in an operation_details object for transparency and debugging.
4. File Naming and Layer Metadata
   File Naming: Output GeoJSON files now use the slugified, unique name (not just a UUID), making URLs and filenames more meaningful.
   Layer Metadata: The created GeoDataObject has:
   name: unique, slugified name
   title: LLM or fallback title
   description: a detailed description including query, input layers, and operation steps
   llm_description: just the LLM’s description or fallback
5. Robustness
   Fallbacks and Uniqueness: If the LLM does not provide a title, a default is constructed. Layer names are guaranteed unique.
   Safe Handling: None values in operation details are filtered to prevent errors.
   Frontend: LayerManagement.tsx
6. Layer Titles in UI
   Drag-and-drop UI: The ghost element now displays layer.title if present, falling back to layer.name.
   Layer List: The main list also displays title (if any) or name, and uses better text wrapping (whitespace-normal break-words) for improved readability.
   Summary of Improvements
   User Experience: Layer names in the UI and download links are now human-readable and descriptive.
   Metadata Transparency: Users and developers can now see exactly what operation was performed, with clear descriptions, in both the backend results and the frontend display.
   Robustness: The system avoids name collisions and gracefully handles cases where metadata might be missing.
   Potential Suggestions
   Tests: Ensure there are tests for the new utility functions (slugify, ensure_unique_name) and for the LLM-driven metadata flow.
   LLM Output Validation: Consider adding stricter validation or error handling if the LLM fails to return the expected JSON structure.
   Documentation: Update any user or developer docs to reflect the new metadata and file naming conventions.
   Conclusion
   This is a well-structured pull request that meaningfully improves both backend and frontend code, making the system more user-friendly and robust. The code changes are clear, add valuable features, and improve maintainability. Nice work!
