fix(hosting): restore macOS tap gestures in offset views

[Kyle-Ye]

Summary

• Restore onTapGesture delivery when an NSHostingView has a nonzero offset in its window by providing the host-to-window root transform.
• Keep gesture hit testing correct when the host or an ancestor moves by invalidating the transform through geometry observation.
• Add regression coverage for coordinate conversion, geometry changes, observer lifetime, and native clicks in borderless and titled windows.

Closes #1083.
