Contributor guide

Research direction
Locate where NSURLSessionTaskPriorityHigh is defined in Apple's open source CFNetwork or header files. Add the missing symbol to Darling's CFNetwork compatibility layer, likely in the relevant source file that exports symbols for NSURLSession task priorities. Consult the Darling build system to understand how symbols are exposed. Test by running WeChat again.
