Fixes the K1, K3 and K10 race: a child could get SIGTERM before it
installed its handler. Author: Darkwing. Reviewer: Dewey (approve,
comment 26873). BUILD-LOG landing entry with gate counts and the
correction to decision 72's probe claim.

Controller, claim store, live-session guard, engine link and seal,
turn tracker, cohort force stop and recovery, client library,
transcript and mediated terminal, with the fake engine and tests.
Fixtures only; no live cutover.
Dewey built it. Darkwing (comment 26690) and Filbert (comment 26694)
approved round 2. Manifest I1-r2-manifest.sha256 (2b48e333, 27 files).
Suites on an export: conversation 152/152, control-board 124, webui 14,
seat 19, chat-00/01/01c checks, and all nine scripts/test-*.sh green.
Follow-ups for I3 are in DEFERRED. Gate E stays with Jason.
