Trending Repos, Analyzed

Every day a GitHub Actions pipeline takes the day's GitHub trending repositories and runs jscpd on each one twice: over every file, and over the code alone, without tests, docs, data, vendored and generated files. The code number is the one worth comparing. The all-files number mostly says how much copied or generated material a repository carries.
