Add Swift/Xcode error stacktrace compression

[jee599]

Add a new error compression pattern for Swift/Xcode stacktraces. Similar to how Node.js, Python, Rust, Go, Java are already handled in src/error_cmd.rs.

Swift stacktraces typically show:

• Framework frames from UIKit, SwiftUI, Combine
• User code frames from the app

Should filter UIKit/SwiftUI/Combine frames and keep user code.
