refactor: 统一 Cargo workspace 与 Windows 依赖

将 applechu、applechu-macros 和 chu-abi 迁入 packages 目录，并把仓库根 Cargo.toml 改为三成员 workspace；集中管理版本、edition、license、共享依赖和 release profile，同时以 applechu 作为默认成员，保持根目录构建命令与 DLL 产物路径不变。

将应用直接依赖统一为 windows-sys 0.59，合并两套 feature 列表并移除 windows-sys-loader 别名；按 0.59 的指针句柄语义迁移 Win32 空句柄、模块句柄和 UART/IO 伪句柄转换。

新增统一的 opaque handle 转换边界与回归测试；workspace 33 项测试、Clippy、release PE32 构建和 x86 Miri strict-provenance 定向测试均通过。
