"""Create Miniflux categories and feeds from feeds.yaml.

Env vars required: MINIFLUX_URL, MINIFLUX_USERNAME, MINIFLUX_PASSWORD.

Idempotent: existing categories are matched by title, existing feeds are
matched by feed_url, both fetched from the API before any create call.
Safe to re-run (e.g. every time the Job runs) — only new entries get
created.
