When PS commanded turnOffAllMachines, executeSequence's interruptible
abort path triggered transitionToState('operational'), which auto-picked
up the queued delayedMove and re-started the pump. Pump bounced
accelerating ↔ decelerating forever and never reached idle.
Clear state.delayedMove at the top of shutdown/emergencystop sequences
so a user-commanded stop cancels any pending move.
Observed live: in pumpingstation-complete-example the basin drained
past stopLevel and equilibrated at ~0.3 m with one pump stuck at min
flow. With this fix pumps shut down cleanly at stopLevel.

Safety:
- Async input handler: await all handleInput() calls, prevents unhandled rejections
- Fix emergencyStop case mismatch: "emergencyStop" → "emergencystop" matching config
- Implement showCoG() method (was routing to undefined)
- Null guards on 6 methods for missing curve data
- Editor menu polling timeout (5s max)
- Listener cleanup on node close (child measurements + state emitter)
- Tick loop race condition: track startup timeout, clear on close
Prediction accuracy:
- Remove efficiency rounding that destroyed signal in canonical units
- Fix calcEfficiency variant: hydraulic power reads from correct variant
- Guard efficiency calculations against negative/zero values
- Division-by-zero protection in calcRelativeDistanceFromPeak
- Curve data anomaly detection (cross-pressure median-y ratio check)
- calcEfficiencyCurve O(n²) → O(n) with running min
- updateCurve bootstraps predictors when they were null
Tests: 43 new tests (76 total) covering emergency stop, shutdown/maintenance
sequences, efficiency/CoG, movement lifecycle, output format, null guards,
and listener cleanup.
