[Feature] Expose CMake commands to Copilot Agent mode

[doxxx]

Request Overview

It would be helpful when working with Copilot Agent mode if CMake commands like Configure, Build, Run Tests, etc. were exposed as tools to the agent. This would allow it to do things like rerun Configure after adding a new source file, run the build to check that the modified code compiles, and run tests to check that they pass.
