fix: move session-end hooks from Stop to SessionEnd

Stop hook fires after every response, SessionEnd fires only when
session actually terminates. This was causing session-end.sh and
evaluate-session.sh to run on every response instead of at session end.

Fixes issue reported by user about hooks triggering every response.
