"""migrate_all.py — 一次性将全部生产 JSON 数据迁移到 mofin.db

运行方式:
    python3 migrate_all.py

迁移映射:
    portfolio.json       → holdings + holding_strategies (from analysis)
    watchlist.json       → watchlist_stocks + holding_strategies (strategy_type='watch')
    candidate_pool.json  → candidates + candidate_score_history
    decisions.json       → holding_strategies (changelog history)
    price_events.json    → price_events
    stock_sector_map.json → stock_sectors
    evaluation.json      → strategy_evaluations
    stock_profiles.json  → stocks (name, exchange, type)
