AI-merge review hangs left activeMergeTaskId/mergeRunning set while
status=reviewing and overseer logEntry noise kept updatedAt fresh, so
self-healing never reclaimed the owner and the board showed no merging
badge. Race merge work with abort, force-abort on pause/reclaim, treat
reviewing as merge-active, and recover on merger agent silence; also
forward PluginRunner into AI merge so grok-cli merger matches chat.
