- Simplified Route class by removing validator functionality - Added AppRouteContext type for better type safety - Added forward method to RouteContext for response handling - Replaced queryRoute with run method for consistency - Improved Server class with proper cleanup methods - Updated Mini class to extend QueryRouterServer properly - Removed lodash-es dependency and nanoid random import - Added deprecation warnings for older methods - Enhanced route handling and middleware execution 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
