Consider disabling module auto-loading during IntelliSense

Module auto-loading during IntelliSense is causing some issues for people, including session hangs and IntelliSense slowness. We use Get-Command to gather information about the currently active IntelliSense result. This causes the module containing the command to get loaded, and if the module misbehaves somehow, it can damage the rest of the session.

We should consider setting the $PSModuleAutoLoadingPreference to "none" before running Get-Command so that IntelliSense details are only gathered for modules that the user has loaded. To make sure we have cmdlet signature details, we could potentially just parse the tooltips of the completions if they're available without loading the module.

首先跟踪使用 Get-Command 收集当前补全结果详细信息的 IntelliSense 路径。确定如何在保留可用 cmdlet 签名详细信息的同时，防止该查询加载模块；当 IntelliSense 不再因模块自动加载而导致会话挂起或变慢时，即视为完成。
