refactor: Makefile 命名规范化，新增顶层便捷命令

统一命名规范为 <namespace>-<action>[-<variant>] 格式：
- 重命名 desktop-mac/win/linux → desktop-build-mac/win/linux
- 重命名 backend-migrate-* → backend-db-*
- 重命名 frontend-build-desktop → desktop-prepare-frontend
- 重命名 embedfs-prepare → desktop-prepare-embedfs
- 重命名 package-macos → desktop-package-mac

新增顶层便捷命令：
- dev: 并行启动开发环境
- build: 构建所有产物
- test: 运行所有测试
- lint: 检查所有代码
- clean: 清理所有构建产物
