Interface ISpeedTracker
Provides read-only access to an actor's current speed in SI, MPH, and KPH units so that HUD displays, data-loggers, and metric calculators can all read speed without coupling to a specific physics back-end.

Remarks
Exposing multiple unit properties rather than a single unit avoids repeated conversion arithmetic in every consumer. The HUD shows MPH for the participant, the data logger records KPH for cross-study comparison, and the AI PID uses SI values directly.
The interface deliberately does not include a setter because speed is always a derived measurement of the physics simulation; callers that need to change speed do so through IMoveable.
