fix(pointer-ring): stabilize repeated click animations

[esphynox]

Summary

Stabilize the pointer-ring animation during rapid repeated clicks by coordinating its interaction state and invalidating stale fade work.

The window now focuses on event routing, scheduling, layer state, and positioning. Animation construction and ring-layer configuration are isolated in dedicated types.
