Fetch & Summarize
Given a URL, fetch its content and return a concise markdown summary.
Steps: 1. Fetch the page with `WebFetch` (or `Bash` with `curl -sL <url> | head -200` as a fallback). 2. Extract the main content — ignore nav, footer, ads, and boilerplate. 3. Return a structured summary with:
- **Title** (the page's `<title>` or heading)
- **One-paragraph overview** of what the page is about
- **Key points** as a bullet list (max 5)
- **Source** — the URL fetched
Do not save or write the fetched content anywhere. Return the summary directly.
