Deep user intelligence workflow. For a given Twitter/X username, returns structured account metadata (location, verification status, blue check date, username history) alongside a month-by-month tweet volume breakdown for the past 12 months. Each month fetches up to 5 pages of search results (up to ~100 tweets per month). Query params: username (string, required) - Twitter/X screen name. Returns data.user (account metadata) and data.tweetCountPerMonth (object keyed by MM-YYYY).
