NK-WP-0056-T11 done: bounded executor core runner

Consumes one admission once through the approval-engine carrier after an
effect-free preflight (validity, source pins, trust, window vs budget,
binding digest, actor, human aal2 approvers), emits run.started, runs steps
with settle-timed checks, reverts on failure with per-revert checks, retries
within attempts, stops on unknown outcomes, honours budget and kill switch,
and emits one value-free receipt (PDP not-evaluated). 22 tests with fakes.
BEA-9 extended to revert steps; examples regenerated.
