0.12.3

Core

• Device management is consolidated onto a single app-wide
  DeviceManager (DeviceManager.shared) instead of separate
  instances in the engine and the welcome model, keeping device
  enumeration and state consistent across the app.

CI / packaging

• Windows: dropped the msys2 path-type inherit.
• Nix flake pinned to the 0.12.2 .deb.

Dependencies

• frida-core / frida-swift bumped.
