refactor(stage5): 合并重复实现,移除失效的演示能力
Excel 导出(原先 4 份各自拼装 workbook) - 新增 src/shared/xlsx.ts 作为唯一实现:文件名统一 .xlsx、sheet 名截断到 31 字符, 对外提供 buildAoaSheet / buildJsonSheet / writeWorkbook / exportAoaSheet / exportJsonSheet。 只收敛"组装与写出"这一层,各调用方仍自行决定列宽、冻结与数字格式,导出样式不变。 - 迁移 assets(内联 json_to_sheet + writeFile)、mileage/xlsx-export、 hydrogen 的两份 helper(prototype-download.ts 与 download-xls.js,均已删除)。 高德地图(原先 2 份近乎逐行复制) - 新增 src/shared/amap.ts:SDK 版本、插件列表、安全码注入、底图参数、 控件位置与热力图色带只在此处定义;两个画布只保留各自的半径/透明度。 - 图例渐变条原先把同一组色值又写了一遍,改为复用 shared 的常量,图例与地图不会漂移。 数值格式化 - 两个下钻视图各自复制了同样的 formatNumber/format(共 42 处调用), 统一到 hydrogen/model/display-format.ts 的 formatFixed;默认路径与既有行为逐字一致。 - 原 display-format.ts 里的 finiteNumber/formatNumber/formatScaled 无任何生产调用方, 只被自己的测试引用;改为 formatFixed + blankForMissing 显式选项, 既保留了"真零 vs 不可用"的区分能力,也不再留无人使用的导出。测试同步重写。 失效的演示能力 - Blur / DemoModeProvider 恒为 enabled=false,等于永久 no-op: 移除 13 个文件里 50 处 <Blur> 包裹(渲染结果不变)、删除 components/Blur.tsx 与 Shell 中的 Provider,调用方直接渲染原表达式。 未做(刻意) - src/lib/cn.ts 不引入 tailwind-merge:全仓只有 2 处调用,不值得新增传递依赖。已在文档说明。 架构守护新增 2 条:只有 shared/amap.ts 可加载高德 SDK; modules/** 不得再出现 book_new / book_append_sheet / writeFile(。 lint / test(137) / build 全绿,可达性仍为 0 未引用文件。
