fix: use env var instead of tmux check for Stop hook scoping

Browse Source 
The tmux display-message approach had edge cases: it could succeed outside
tmux, fail on first iteration, or behave differently depending on tmux
socket state.

Replace with AGENT_LOOP_ACTIVE env var exported by loop.sh. CC sessions
spawned by the loop inherit it; interactive CC sessions don't. Simple,
no external dependencies, no race conditions.
