 ### New Feature
 * Add experimental support for Copilot descriptions in hover tooltips, controlled by the `C_Cpp.copilotHover` setting. This feature is currently off by default and may be subject to A/B experimentation. To opt-out of Copilot Hover experiments, set `C_Cpp.copilotHover` to `disabled`.
