Remove -T as that stops my perl finding my local::lib, ergo I don't find pod coverage and the test doesn't run. Bump required pod::coverage version so that POD is found for ::Deferred, and switch to manually getting a list of modules and manually filtering out ::Traits?::, as these are buried in other files and have no methods, so need no individual docs
