/**
 * Patch: fire a Gitea workflow_dispatch after each Micropub create/update/delete/undelete.
 *
 * Gitea Contents API commits (what store-github does) do NOT trigger `on: push`
 * CI workflows. This patch fires a workflow_dispatch to the blog repo after each
 * successful Micropub action so the Eleventy build runs immediately.
 *
 * Env vars read at runtime (all have defaults):
 *   GITEA_BASE_URL       Internal Gitea API base, e.g. http://10.100.0.90:3000/api/v1/
 *   GITEA_CONTENT_USER   Org/user that owns the blog repo (e.g. giersig.eu)
 *   GITEA_CONTENT_REPO   Blog repo name (e.g. indiekit-blog)
 *   GH_CONTENT_TOKEN     Gitea PAT with Actions write permission
 *   GITEA_DISPATCH_WORKFLOW  Workflow filename, default deploy.yml
 *   GITEA_DISPATCH_REF       Branch to dispatch on, default main
