"""
도전과제 시스템 — 357개 자동 평가.

설계:
- 각 도전과제는 dataclass `Achievement` + 평가 함수 (db) -> (progress, target).
- 평가자는 5분 throttle로 호출되어 미획득 도전과제만 검사.
- 신규 잠금 해제 시 main_window의 `notify_achievement_unlocked` 시그널 emit.
- 진행도(progress)는 부분 달성 표시용 — UI 게이지에 활용.

데이터 소스:
- work_records: 출근/퇴근 기록
- overtime_bank, overtime_usage: 적립/사용
- leave_records: 연차
- break_records: 외출/식사
- holidays: 공휴일
- settings: 사용자 메타 + 뷰 카운터
- notification_log: 휴식 권고 카운트
