feat: 构建系统重构 + VCHSM 架构迁移 + 右键菜单修复 + 尺寸参数统一

## 构建、打包与分发系统重构 (build/)

- 构建系统收敛至 build/ 目录：build.mjs + electron-builder.js + 6 个脚本

- electron-builder 配置从 package.json 提取为 build/electron-builder.js

- 新增 --edition (personal/enterprise) 和 --channel (stable/beta/alpha) 参数

- OSS 路径按渠道隔离

- 新增 pre-build-check.mjs：Git/CHANGELOG/版本/环境变量校验

- 新增 bump-version.mjs：版本号管理 + CHANGELOG 自动生成

- updater.ts 发送 channel/edition/deviceFingerprint

- 新增 src/shared/utils/rollout.ts 灰度测试工具

- 新增 10 条 NPM 脚本

## VCHSM 五层架构迁移

- 7 个业务模块 + ~500 处导入路径同步

## 修复

- MediaCardContextMenu 改用共享 ContextMenu 组件

- ComboBox 尺寸参数显示统一 (size-format.ts)

## 文档

- UpdateA.md / build/README.md / README.md / .env.example 更新
