feat(state): honor sequenceAbortToken so external aborts cleanly break sequences

Consumer half of the abort-token mechanism added in generalFunctions
state.js. executeSequence captures host.state.sequenceAbortToken at
entry, then re-checks before every state transition and after the
optional ramp-down. If MGC (or any external caller) bumps the token
mid-sequence, the loop bails out cleanly — no more barge-through where
a pre-empted shutdown advances through stopping → coolingdown after a
fresh demand has already engaged the pump.

Without this the MGC rendezvous planner can't reliably re-dispatch a
pump that's mid-shutdown: the new flowmovement claims the gate, but
the old shutdown's for-loop keeps running on microtasks and steps the
FSM into idle/off underneath it.

Also: wiki regen following the same visual-first 14-section template as
the other EVOLV nodes — Reference-{Architecture,Contracts,Examples,
Limitations}.md split with _Sidebar.md index.
