The review showed the added dispose case was a placebo (dispose in the same
tick as run means SIGTERM hits the group before the program body runs; the
group-emptied arm is already deterministically covered by the same-group
survivor case, which this removes the v8 ignore for). The test is deleted; the
stale silently-discards comment in the boundary test now says rejects; the
README Known Limitations gains the late-log-frame-drop and host-side
binding-value-memory entries. Pairing re-recorded.
