  # This is a "join node" which depends on all prior workflows. The merge queue,
  # for example, gates on this to ensure that everything has executed
  # successfully.
  #
  # Note that this is required currently for odd reasons with github. Notably
  # the set of checks to enter the merge queue and leave the merge queue must
  # be the same which means that the "build" step for example shows as skipped
  # for PRs but expands to many different steps for merge-queue-based PRs. That
  # means that for that step there's no single name to gate on, so it's required
  # to have a "join" node here which joins everything.
  #
  # Note that this currently always runs to always report a status, even on
  # cancellation and even if dependency steps fail. Each dependency tries to
  # cancel the whole run if it fails, so if a test matrix entry fails, for
  # example, it cancels the build matrix entries too. This step then tries to
  # fail on cancellation to ensure that the dependency failures are propagated
  # correctly.

  # The purpose of this jobs is to watch for changes on the `release-*`
  # branches of this repository and look for the term
  # "automatically-tag-and-release-this-commit" within merged PRs/commits. Once
  # that term is found the current version of `Cargo.toml`, the `wasmtime-cli`
  # Cargo.toml, is created as a tag and the tag is pushed to the repo.
  # Currently the tag is created through the GitHub API with an access token to
  # ensure that CI is further triggered for the tag itself which performs the
  # full release process.
  #
  # Note that this depends on the `ci-status` step above which is the "join"
  # point of this workflow for when everything succeeds. the purpose of that is
  # so that the tag is only created after the aftifacts have been uploaded for
  # this workflow as the `publish-artifacts.yml` workflow will download these
  # artifacts and then publish them to the tag.
