Description

Tool.Run and related should make stdout and stderr available so that some analysis is possible on failure. Currently it calls ProcessExitCode which throws a simple CakeException.

Ideally, it would capture stdout and stderr and throw a CakeProcessException, or similar, that has additional properties for exit code, stdout and stderr.

Contributor guide

Research direction
Familiarize yourself with the Cake build system. Locate the Tool.Run method in src/Cake.Core/Tooling/Tool.cs. Understand how ProcessExitCode is called and the exception thrown. Design a new CakeProcessException class that captures exit code, stdout, stderr. Modify Tool.Run to capture output using Process.Start with RedirectStandardOutput and RedirectStandardError. Update tests to verify the new behavior.
