JSON Debugger Visualizer in Visual Studio 2013

Introduced a JSON Visualizer for the Visual Studio debugger, which displays JSON encoded strings in a treeview control. This visualizer allows for meaningful user interaction such as search, highlight, copying key-value pairs, and copying paths. It handles invalid JSON formats by displaying an error message and the string in plain text. The visualizer works across all languages and project types supported by the Visual Studio debugger.
