feat: implement color and shape leaf hit testing

[Kyle-Ye]

Summary

• Implement ColorView hit testing and description attributes.
• Add ShapeStyledLeafView hit testing, content paths, and responder updates with clear-style handling and background selection.
• Use PlatformPoint buffers across content responders and forward the Path point-array overload to its buffer overload.

Validation

Focused, isolated behavior checks passed for color containment and shape responder forwarding.

👀 Human review needed

Justification

This PR implements new functional hit-testing and geometry logic in the core event/render path — it is not a docs, formatting, or otherwise mechanical change, so it falls outside automatic low-risk approval.

Key factors:

• Package API surface change. The package protocol ContentResponder.contains(points:size:) signature and its default implementations change from UnsafeBufferPointer<CGPoint> to UnsafeBufferPointer<PlatformPoint>. PlatformPoint is a typealias for CGPoint, so this is type-compatible, but it touches every conformer (ColorView, RendererLeafView default, ShapeStyledLeafView, ShapeStyledResponderData) and warrants a maintainer's confirmation.
• New responder wiring. ShapeStyledResponderFilter (a StatefulRule) now feeds outputs.preferences.viewResponders and drives interactive hit testing via LeafViewResponder/ContentResponderHelper. Behavioral logic in the attribute graph has correctness implications that benefit from human review.
• Incomplete path branch may trap at runtime. ShapeStyledLeafView.contains(...) routes the .path case to path.contains(points: UnsafeBufferPointer<PlatformPoint>, eoFill:origin:), but that buffer overload in Path.swift is still _openSwiftUIUnimplementedFailure(). The newly added array overload only forwards to it, so real path-shape hit testing will trap if exercised; only the non-path (frame-rectangle) branch is functional.
• Inline containment divergence. ColorView.contains reimplements containment inline (min($0.x, $0.y) >= 0 && $0.x < size.width && $0.y < size.height) instead of reusing the existing CGSize.contains(point:) helper. It is functionally equivalent, but the divergence is worth a reviewer's eye.

Static analysis only; build and tests are owned by CI.

This new shape hit-test path calls Path.contains(points:eoFill:origin:), but that overload still ends in _openSwiftUIUnimplementedFailure(). Any hit test whose point is inside a path-backed shape's frame will now trigger a precondition failure instead of returning a containment mask.

Severity: high

🤖 Augment PR Summary

Summary: This PR implements hit testing for color and shape-backed leaf views.

Changes:

• Adds opaque-color containment and non-clear color description attributes to ColorView.
• Moves content-responder point buffers to PlatformPoint.
• Adds a buffer-based Path.contains overload, with the array overload forwarding to it.
• Implements shape leaf containment, including fill-rule and frame-origin handling.
• Provides shape content paths and suppresses responder paths/hits when resolved styles are clear.
• Registers a stateful shape responder filter when view responders are requested.
• Keeps responder data synchronized with animated size, position, transform, view, and styles.
• Selects a nonempty background shape for hit testing when a shape leaf supplies one.
• Refactors display-list construction while preserving its conditional creation and identity behavior.

Technical Notes: The changes make hit-testing masks operate on transformed local point buffers and use the existing responder-helper invalidation flow.
