🤖 Augment PR Summary

Summary: This PR replaces the previous placeholder image types with a more complete image resolution pipeline centered around a new GraphicsImage and Image.Resolved.

Changes:

• Moved GraphicsImage out of DisplayList (removing the empty stub) and introduced a new Sources/OpenSwiftUICore/View/Image/GraphicsImage.swift with content variants, sizing/orientation helpers, and style resolver integration.
• Implemented CGImageProvider.resolve(in:) to produce Image.Resolved, including dynamic range computation and redaction behavior.
• Added ResolvedImage.swift defining Image.Resolved, layout metrics scaffolding, and basic provider/view conformances (some still WIP).
• Implemented previously-WIP image modifiers: interpolation, antialiasing, and resizable behavior by mutating the resolved GraphicsImage.
• Added _ShapeStyle_ResolverMode initializer for symbol style masks and updated orientation utilities (mirroring + horizontal detection) used in size calculations.
• Introduced an ImageAccessibilityProvider hook in graph/view inputs and added CoreGraphics private shim support for querying CGImage headroom.

Technical Notes: The new flow computes effective HDR constraints via ImageResolutionContext.effectiveAllowedDynamicRange(for:) and uses EnvironmentValues.shouldRedactContent to substitute a low-opacity foreground color when redacting.
