SwiftUI previews crash after agent edits property wrappers

Agent converts @StateObject to @State (or reorders wrapped properties) as part of an 'observability migration' and every preview in the file dies with 'Compiling failed: cannot preview in this file' or a XCPreviewAgent crash. Builds fine, runs fine on device — only previews break.
