feat: implement simulation clock with configurable time multiplier

Broker-driven clock that broadcasts periodic heartbeat ticks to all
peers in a mesh. Speed is configurable from x1 (real-time, 60s ticks)
to x100 (600ms ticks) for load testing simulations. Auto-pauses when
the last peer disconnects.
