v1.1.0: better-sqlite3→sql.js迁移 + 6项UI/代码修复

迁移:
- better-sqlite3(原生C++) → sql.js(WASM纯JS), 兼容Node 24
- database-service.ts: PreparedStatement包装器保持API兼容
- main.ts: initialize()改为async/await
- 移除@electron/rebuild和@types/better-sqlite3依赖
- 新增.npmrc阿里云镜像加速

UI/代码修复(任务1-6):
1. TerminalView: 清理111行调试日志(645→534行)
2. 设计系统: cyan/slate→accent-blue/dark-*颜色统一(FileRow/TransferItem/Breadcrumb/ContextMenu)
3. StatusBar: 重写接入实时连接状态,三区布局
4. SessionDialog: 私钥浏览按钮添加onClick处理
5. WelcomeView: 真实session数据替换硬编码假数据
6. SFTPView: emoji→Lucide图标(FolderOpen/Upload/Download/Trash2)

构建验证: tsc零错误 + vite build成功(Node 24.14.0)
