v1.23.1

• iOS: PamHeldPanGestureRecognizer imports UIKit.UIGestureRecognizerSubclass,
  which declares the touchesBegan/touchesMoved/reset overrides it uses;
  without it the iOS host does not compile ("method does not override any
  method from its superclass"). Found by a Linux Swift 6.4 pre-check (every
  Swift file parses; Foundation-only sources type-check); a full Xcode build
  still needs the Mac.
• No PHP API, protocol identifiers, Android code or dependency requirements
  changed. Rebuild the iOS host; see migration notes.
