two_user.rs started its flagged servers with env_clear plus a Unix PATH
and HOME, no SystemRoot: on Windows Winsock cannot start without it, so
the --http door failed to bind (the server says so on stderr and serves
its pipes only, which is why "ready" still came). The tests now use the
harness's clean_env, as do evidence.rs's extract and the viewer's
command_line test. main (a8ce2e7d) merged in.
