Function extractReviewFromLog

* Extract review content from the remote session log. * * Two producers, two event shapes: * - bughunter mode: run_hunt.sh is a SessionStart hook; its echo lands as * {type:'system', subtype:'hook_progress', stdout:'...'}. NCode never * takes a turn so there are zero assistant messages. *

(log: SDKMessage[])

 * appears once at the end of the run so reverse iteration short-circuits.
