refactor(B组清理): 归档strategy_tree/branch_evaluator/prune_branches/branch_scanner,detect_scenario→market_regime

- 归档4个B组模块: strategy_tree.py/branch_evaluator.py/prune_branches.py/branch_scanner.py
  按方法论：只有重评才能改信号和操作，B组的分支扫描/评估/剪枝越权
- stale_push_wlin.py: detect_scenario→market_regime.load_market_regime()
- strategy_lifecycle.py: detect_scenario→market_regime.load_market_regime()，筹码权重改用温区
- import_holding_xls.py: 移除init_default_branches调用(分支概念已移除)
- per_stock_reassess.py: 移除init_default_branches调用(分支概念已移除)
- 清理mofin_db.py/strategy_lifecycle.py残留注释引用
- 关键脚本语法全部通过
