貢獻者指南

研究方向
Investigate how Angular CDK overlay's lifecycle interacts with router navigation when RouteReuseStrategy is used. Look at the overlay ref counting mechanism in the OverlayRef and how it handles detach on route change. Check if there is a missing cleanup when the route is reused. Consider examining the following files: overlay ref.ts, overlay container.ts, and the RouterModule setup.
