## Description

Add Apple Pencil drawing with PKCanvasView, PKToolPicker, PKDrawing serialization/export, stroke inspection, and PencilKit/PaperKit handoffs. Use when building drawing apps, annotation features, handwriting capture, signature fields, content-version-safe ink workflows, or Apple Pencil-powered experiences on iOS/iPadOS/visionOS.

# PencilKit

Capture Apple Pencil and finger input using `PKCanvasView`, manage drawing
tools with `PKToolPicker`, serialize drawings with `PKDrawing`, and wrap PencilKit in SwiftUI.
