Show overlays only after activation completes

The local probe confirmed activation is asynchronous on macOS 26:
isActive flips on a later runloop tick, so overlays shown in the same
tick as activate() belong to a still-inactive app and misses clicks.
Delay overlay creation by a tick and log the activation state at show
time.
