Summary by CodeRabbit
Walkthrough本次修改为 Sidecar、USB/IP 和 HIDMaestro 下载流程增加统一的 1 MiB 异步写入缓冲区，并在下载完成或校验前刷新输出。 ChangesDualSense 下载写入缓冲
Estimated code review effort: 2 (简单) | ~10 分钟 Merge Risk: 🔵 Low · up to The PR hardens manifest-size enforcement and makes large downloads asynchronous before verification or installation. Merge readiness is low risk but requires owner awareness because redirect loops can still tie up a request until timeout, and component-source status information is still not shown to users.

879-898: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win下载循环在异步任务中使用同步文件写入。
File::create与output.write_all都是std::fs的阻塞调用。HIDMaestro 归档约 119 MB，Sidecar 归档也可能很大。每个数据块都在 Tokio 工作线程上执行阻塞写入，会阻塞该线程上的其他任务，例如状态查询与进度事件。建议改用tokio::fs::File与AsyncWriteExt::write_all，或把写入放入spawn_blocking通道。依据路径说明检查了异步任务生命周期与阻塞调用：「重点检查 IPC 命令的输入校验与权限边界、错误处理、进程和文件系统操作、异步任务生命周期」。

load_component_manifest使用fs::read_to_string一次读入整个文件，没有大小上限。归档内的 payload manifest 已经用MAX_SIDECAR_PAYLOAD_MANIFEST_BYTES限制。若 Sunshine 安装目录中的components/dualsense.json被替换为超大文件，状态查询会分配同等内存。建议先检查fs::metadata的长度，再读取。🛡️ 建议改法

reqwest 0.12.28的Policy::custom不提供默认跳转上限。允许列表内的主机形成循环时，下载请求可能持续到超时。请使用attempt.previous().len()限制跳转次数，并在超限时调用attempt.error(...)。
attempt.stop()会返回 3xx 响应。error_for_status()只拒绝 4xx 和 5xx，因此当前代码可能继续处理被拒绝的重定向，并最终报告DS5-DL-002大小错误。请使用attempt.error(...)或在响应处理前显式拒绝 3xx。🤖 Prompt for AI Agents

Learning: In src-tauri/src/gui_auth.rs, the methods `current()` and `refresh()` may perform Windows named-pipe I/O and include retry sleeps, so they can block. Only call them from synchronous code. For any async call chain (e.g., from async functions in src-tauri/src/sunshine.rs), use `current_async()` and `refresh_async()` instead, which should route the blocking work via `tokio::task::spawn_blocking` to avoid blocking Tokio worker threads. During review, flag any call to `current()`/`refresh()` from async contexts and require switching to the *_async variants.
