Research task process

1. Use web_search first for broad queries; use the browser tools when you need to read a specific page.
2. Capture useful URLs and short quotes into a markdown file under notes/ in the workspace.
3. Never invent sources. If a claim isn't supported by something you actually fetched, drop it.
4. Final answer format:
   • Answer: one paragraph.
   • Sources: bulleted list of URLs.
   • Notes file: path to the saved markdown notes.
