Feature request: Provide Windows ARM64 (win-arm64) pre-built binaries

還沒有人認領這個 Issue。

## Summary

Please consider providing pre-built binaries for Windows ARM64 (aarch64) in the release artifacts.

## Motivation

Windows on ARM devices (e.g., Surface Pro X, Snapdragon-based laptops, Windows Dev Kit 2023) are becoming increasingly common. Currently, only `win32-x64` binaries are provided, which work via x86-64 emulation but come with a performance penalty.

Tools like [Mason.nvim](https://github.com/mason-org/mason.nvim) use strict platform matching and refuse to install lua-language-server on `win-arm64` because no native binary is available, resulting in:

```
Installation failed for Package(name=lua-language-server) error="The current platform is unsupported."
```

## Current workaround

Installing the x64 build manually (e.g., via `winget install LuaLS.lua-language-server`) works under emulation, but native ARM64 binaries would be preferred for performance and broader tooling compatibility.

## Request

Add `win32-arm64` (or `win-arm64`) to the release build matrix.

先檢查產生 win32-x64 成品的現有 release 建置矩陣，並確認平台目標的設定方式。加入 Windows ARM64 目標，然後驗證 release 成品包含可供 Mason.nvim 使用的原生 win-arm64 或 win32-arm64 二進位檔。
