feat(strategy): filter_history 列依赖 AST 推导 — 消灭回测全量兜底 (P1a)
- feature_deps: 追踪 pl.col/cols 常量引用推导输入列; 动态列名/pl.all/cs.*
等不可证明形态一律返回 None, 保持全量兜底 (fail-closed, 宁慢不错列)
- engine: REQUIRED_FEATURES 缺失且存在动态过滤时加载期自动推导
- bench_feature_resolution: legacy(空依赖) vs 推导 的解析宽度对比基准
- 实测: 看板策略等 4 个无声明策略 37→3~5 指标列 (宽度比 7~12x);
short_term_top10 动态列名循环正确保持兜底
