step_executor gains three dispatch modes: pulse (default), hold
(hold_until_confirm), and value (transfer_move_to writes the target
station's code). The engine now sends step.stop_command_role whenever
cancel_on_fault is true on Faulted entry, and threads a target-station
lookup ahead of dispatch. A new simulate module patches the resolved
confirm signal after a short delay when SIMULATE_PLC is set, so
segments can be driven end-to-end without a real PLC.

Wires AppState with EventManager, SegmentRuntimeStore, ResourceRegistry
and an engine supervisor that idles until P1 lands the segment schema.
The run() bootstrap connects enabled sources, installs a Ctrl+C handler,
and disconnects on shutdown, matching the feeder app lifecycle. The
router exposes /ws/public, /ws/client/{id}, simple_logger middleware
and a permissive CORS layer.
AppEvent covers the full ops.* taxonomy from the spec; resource lease
tracking includes heartbeat timestamps for the §7 recovery strategy and
has two unit tests for acquire/release semantics.
