feat: Sprint C-2 + C-3 — 팀 Git 중앙 Repo + 리포트

team.py:
- init_team(): repo clone + .team-config.json 로드 + 보안 규칙 병합
- team_stats(): 팀원별/프로젝트별 세션 통계
- print_team_stats(): 터미널 대시보드 출력
- team_weekly_report(): 팀 주간 마크다운 리포트 생성

cli.py:
- team 서브커맨드 (stats, weekly, monthly, init, add-member)
- init --team <url> 옵션 (팀 모드 초기화)
- delete --last / --session (세션 삭제)

.team-config.json 스키마:
- team_name, members, roles (member/lead/admin)
- security (mask_paths, content_filters, required_secret_scan)
