Contributor guide

Research direction
Investigate the assertion in QMUI's UINavigationBar+QMUI category. The issue occurs when modifying navigation bar styles before it is added to the window. Ensure that style changes are deferred until the navigation bar is in the view hierarchy, or use QMUI's safe style modification methods.
