셸 스크립트 안정성 개선 (실행 흐름 변경 없음)

- stop.sh/stop-mlx.sh: kill -9 → SIGTERM 후 2초 대기, 미종료 시 SIGKILL fallback
- stop-mlx.sh/stop-ollama.sh: docker ps에 2>/dev/null 추가 (Docker 미실행 시 에러 억제)
- stop-ollama.sh: brew 명령어 존재 여부 체크 추가
- setup.sh: VRAM_MB 빈 값 방어 코드 추가 (set -e 크래시 방지)
- setup-ollama.sh: sleep 3 → 최대 15초 readiness 체크 루프로 교체
