killAll

Kill every in-flight eval on this lane. PUSHED from ClientAuthProbe.observe — on every client tick the gate reads denied — rather than polled by the eval itself: this lane bakes in no scriptguard, and a snippet that never yields runs to completion inside ONE EvalTask.pumpStep, so there may be no boundary at which the eval could ever notice a revoke.

Entries stay in live until their worker unwinds, so an already-killed task is EvalTask.nudged instead: one interrupt() is not reliably enough, and nudgeAll is the retry. A step that swallows every interrupt and never blocks cannot be stopped — the JVM's ceiling, not this lane's.
