Add RequestContext.ClearHttpCache() and DownloadItem.IsPaused from CEF SDK 144

[jozefizso]

Summary:

• IRequestContext.ClearHttpCache() wraps the CefRequestContext::ClearHttpCache() method, allowing callers to clear the HTTP cache for a given request context.
• DownloadItem.IsPaused exposes the pause state of the downloaded item via CefDownloadItem::IsPaused()

Changes:

• Add the DownloadItem.IsPause property
• Add the RequestContext.ClearHttpCache(callback) method

📝 Walkthrough

Walkthrough

CefSharp adds two capabilities: an asynchronous ClearHttpCache API on RequestContext that accepts an optional completion callback, and download pause state tracking via a new IsPaused property on DownloadItem. The implementation spans managed C#, C++/CLI bindings, and native CEF integration.

Changes

HTTP Cache Clearing and Download State

Layer / File(s)	Summary
ClearHttpCache API Contract and Managed Implementation CefSharp/IRequestContext.cs, CefSharp.Core/RequestContext.cs	IRequestContext interface declares ClearHttpCache with optional ICompletionCallback parameter; managed RequestContext.cs provides a public wrapper that delegates to the underlying C++/CLI implementation.
ClearHttpCache C++/CLI Binding and Ref Assembly CefSharp.Core.Runtime/RequestContext.h, CefSharp.Core.Runtime/RequestContext.cpp, CefSharp.Core.Runtime.RefAssembly/CefSharp.Core.Runtime.netcore.cs	RequestContext.h declares the native method with XML documentation; RequestContext.cpp implements disposal validation, optional CefCompletionCallbackAdapter wrapping, and delegation to the native _requestContext; the ref assembly adds the corresponding public virtual method signature.
Download Pause State Tracking CefSharp/DownloadItem.cs, CefSharp.Core.Runtime/Internals/TypeConversion.h	DownloadItem gains an IsPaused boolean property with documentation; TypeConversion.h maps the native download pause state via downloadItem->IsPaused() into the managed item->IsPaused field during type conversion.

Poem

🐰 A cache most clear, now swiftly swept,
And downloads paused, their states all kept,
Through C# down to CEF's domain,
The bindings dance in binding's chain,
With callbacks kind, completion's grace,
We've cleared the way at lightning's pace!
