- Updated the backend documentation in CONTRIBUTING.md and README.md to reflect changes in application structure and API endpoints. - Enhanced the frontend components in MapView.vue for better handling of context menu actions. - Added new types and interfaces in TypeScript for improved type safety in the frontend. - Introduced new utility classes for managing characters and markers in the map. - Updated .gitignore to include .vscode directory for better development environment management.
