Fix global Proc leak, add CI, and minor cleanups

Remove Proc.send :include that leaked methods globally by inlining
_test_pass/_test_fail to avoid send (which ignores refinements).
Add GitHub Actions CI for ruby head, 4.0.2, 3.4, truffleruby, jruby.
Fix typo (lamdba), use $stderr, HTTPS homepage, drop deprecated test_files.
