- 新增 TUSHARE_USE_CUSTOM_API / TUSHARE_API_URL 环境变量配置 - 新增 _custom_api_call() 方法，通过 HTTP POST 调用自定义 Tushare API - 所有数据接口（实时行情、历史K线、基本面等）优先走自定义API，不可用时降级到官方API - 清理代码中多余控制字符和冗余注释 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
feat: 添加 Tushare 自定义 API 支持，支持自定义 API 端点调用与自动降级
- 测试连接时优先检查 TUSHARE_USE_CUSTOM_API 环境变量 - 配置了自定义 API 时，测试请求走自定义端点而非官方 tushare.pro - 未配置自定义 API 时保持原有的官方 API 测试逻辑 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
fix: Tushare 测试连接支持自定义 API
…bug; add data quality gates for analysis pipeline - Fix tushare_adapter.py: _normalize_symbol → _normalize_ts_code, causing K-line API to return empty data for all A-share stocks (e.g. 601127) - Add data quality checks (data_quality.py) to terminate analysis when all data sources fail, preventing hangs in fundamentals/market/news analysts - Update conditional_logic.py, agent_states.py, research_manager.py to support data_all_failed flag for early termination - Remove dead custom API code paths from tushare_adapter.py Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

fix: K-line chart display + data quality gates for analysis pipeline
核心修复： 1. PB/PE 价格修复：当 MongoDB 不可用时，价格从默认值 10.0 降级为从 app cache (market_quotes) 获取真实股价，修复 PB=0.42x（应为 3.46x）的严重误判 2. 价格提取修复：_generate_fundamentals_report 增加对 "最新价格:" 格式的兜底提取， 兼容 get_china_stock_data_unified 返回的数据格式 3. 净利润单位修复：_extract_quarterly_financials 智能判断 AKShare 返回值的单位 （元 vs 万元），修复 61,054.53 亿元的单位转换错误 4. 全链路事实约束：在 9 个 agent（Fundamentals Analyst、Bull/Bear Researcher、 Research Manager、3 Debaters、Risk Manager、Trader）的 prompt 中注入 6 点 反编造事实约束，杜绝 LLM 编造财务数据、未来事件等 5. 前端空代码防护：Detail.vue、Favorites、Screening 增加空股票代码守卫， 消除 "股票代码不能为空" 错误提示 验证结果（第二次分析）： - PB: 0.42x → 3.46x ✅ - PE: 23.3x → 190.8x ✅ - 净利润引用: 全部为正确的 7.54亿元 ✅ - 无编造未来事件 ✅ Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
