🤖 Augment PR Summary

Summary: Adds SwiftUI-compatible transient gesture state tracking to OpenSwiftUI via a new @GestureState property wrapper and an updating gesture modifier.

Changes:

• Introduces GestureState<Value> as a DynamicProperty backed by State, with configurable reset behavior via a fixed Transaction or a reset closure.
• Adds Gesture.updating(_:body:) to attach an updating callback that mutates a transient state value as gesture values change.
• Implements GestureStateGesture<Base, State> as a PrimitiveGesture wrapper around an originating gesture.
• Introduces an internal GestureStatePhase rule that drives updates, tracks reset seeds, and resets the state when the gesture ends/fails or when the attribute is removed.
• Marks the phase attribute as transactional/removable and opts into changed-callback handling via input options.
• Adds a small test suite covering basic wrapper behavior and that updating produces a GestureStateGesture.

Technical Notes: The implementation uses AttributeGraph rules (ResettableGestureRule, RemovableAttribute) and enqueues state writes via Update and/or GestureGraph depending on inputs.
