Xamarin.Forms Renderer to .NET MAUI Handler Migration Skill

Purpose

Use this companion skill to migrate Xamarin.Forms renderer-based UI customizations to .NET MAUI handler architecture with clear risk tracking and validation.

This skill focuses on:

1. Detecting custom renderers, effects, and platform-specific native view customizations.
2. Mapping renderer responsibilities to MAUI handler/property/command mappers.
3. Scaffolding handler classes and platform partial implementations.
4. Producing a manual action backlog for high-risk native mappings.
