0.4.0

Added

• @AutoEquatableView gives reusable SwiftUI views an equality boundary when
  their parent-owned inputs can be compared. Views with closures, bindings,
  replaceable observable sources, or explicitly skipped content keep ordinary
  update behavior. This avoids retaining stale actions or child views.

Changed

• Breaking for older development toolchains: Pin swift-syntax 604.0.0,
  aligned with Swift 6.4. Version 0.4.0 is validated with Xcode 27.0 and
  Apple Swift 6.4. Use Xcode 27.0 for this release; projects that must stay on
  Xcode 26.4 can continue using AppMacros 0.3.0. The deployment minimum stays
  iOS 26 / macOS 26.
