Rene De Ren 3c7d54e9c3 Add 4 cross-node tests closing PS↔MGC integration gaps ...

- ps-mgc-flow-contract: asserts PS's view of MGC outflow equals the live
  per-pump aggregate at every tick. Currently FAILS — exposes that
  MGC's flow.predicted.downstream reverts to optimalControl's bestFlow
  target after handlePressureChange writes the correct flow.act, leaving
  PS with stale outflow values. The mirror added in dc27a56 is necessary
  but not sufficient.

- dead-zone-signal: asserts the Schmitt-trigger transitions
  (engaged 100% → keep-alive 1% → off 0%) across startLevel↓/stopLevel↓
  with proper rising-edge re-arm. Currently PASSES.

- inflow-overcapacity-stability: 45 s sim at 2× station capacity;
  asserts pumps don't thrash or park in accelerating residue. Currently
  FAILS — pumps end up at ctrl=0 in 'accelerating' state, suggesting
  the residue-unpark fix doesn't fully cover steady-state over-capacity.

- realistic-startup-timing: re-runs the varying-demand-during-startup
  scenario with PRODUCTION-default state.time (starting=10s, warm=5s)
  instead of the 1-2 s used elsewhere. Currently PASSES — confirms the
  dispatch-reorder fix holds under realistic transition windows.

Honest summary: 2 pass, 2 fail. The two failures expose genuine
remaining defects in the PS↔MGC measurement contract and the
residue-unpark policy. They're committed FAILING so the bugs are
captured under version control until the underlying fixes land.
