Google News RSS items often have no description or content — just a
title. This left the LLM with insufficient context, resulting in empty
ai_summary fields.
When the stored content is sparse (<100 chars or matches the title),
build_summary_prompt() now fetches the actual article page via
wp_remote_get(), extracts text from <article>/<main> tags, and feeds
it to the LLM. Gracefully falls back to title-only if the fetch fails.
