task-2694+1 NORMAL_CALLBACK_REGISTRATION_ENFORCEMENT MT-7 integration 회귀.

tests/conftest.py 가 /home/jay/workspace 를 sys.path 에 먼저 삽입한 뒤
무관한 import 사슬에서 dispatch / utils 패키지가 live workspace 본으로
캐싱될 수 있다. 본 conftest 는 worktree 본을 강제 로드하기 위해
- sys.path[0] 를 worktree root 로 보장
- dispatch / utils 패키지가 live workspace 본으로 캐싱돼 있으면 제거
한다.
