Subject: [PATCH] ci: post README announcements to discord

entries and posted to the discord channel.

+name: Webhook Announcements
+
+# invoke the common webhook-announcements workflow, scanning README.
+#
+# Two modes:
+#
+#   * push: diff on "## Announcements" section exercises the
+#     real before..after detection and post to discord channel.
+#
+#   * workflow_dispatch: a manual live run. Optionally provide an arbitrary webhook URL and
+#     it POSTs for real. By default it diffs against the git empty tree, so every
+#     announcement currently in the fixture is posted — no need to craft a diff.
+#
+# NOTE: the webhook URL you type is a workflow_dispatch input and is therefore
+# visible in the run's UI/logs. Use a throwaway test webhook (and/or rotate it
+# afterwards), not the production go-openapi webhook.
