A failed clang-tidy check now runs once more with --fix and uploads the
patch as the clang-tidy-fix artifact; the check still fails. /bot
fix-tidy downloads that patch for the PR's latest commit, checks it adds
only includes to C++ files the PR changes, and posts one review: a
one-click suggestion for each include on a line the PR's diff shows, and
the whole patch with a git apply command. Nothing is pushed and no PR
code runs in the bot, so the PR's author can run it too and no token is
needed.
