Subject: [PATCH] Announce pull requests that need action to Slack

Pull requests here, Dependabot's included once it has a workflow to update, went unnoticed until
someone opened the repository.  The shared announcer posts one opened or reopened that is not a
draft, or a draft marked ready for review, to #l337-org, and skips forks.  It is this
repository's first workflow, so a Dependabot configuration for GitHub Actions comes with it, and
the instruction file no longer says there are no workflows.

+It has no application code, no dependencies, and no CI - just the markdown files below, the
+org's public profile page, and one workflow, `.github/workflows/announce-pull-requests.yaml`,
+which posts each pull request that needs action to Slack through the shared announcer in
+`L337-org/github-workflows` (`.github/dependabot.yml` keeps its reference up to date). It is not a mirror of another repo's instructions file; unlike
 repos like `docker-mcp` and `send-to-influx`, there is no paired `CLAUDE.md` for this one to
 track.
