Mechanical fix for the 4×-recurring execution-mode menu ask (kaizen 2026-06-10).
A Stop hook reads the transcript and, if the final assistant message presents the
"subagent-driven vs inline — which approach?" menu, blocks the turn and tells the
model to proceed subagent-driven (boma's standing preference). Fails open,
respects stop_hook_active (no loop), tight match signature (no false positives on
meta-discussion). Pipe-tested across 5 scenarios. Activates next session
(settings watcher only tracks files present at session start).
