browser task

Loads one https page in a real headless browser and performs up to eight steps on it: click, fill, select, check, uncheck, wait, wait_for_selector. Returns a per-step log saying what was attempted and whether it succeeded, plus the final URL, title, visible text, links, form structure and an optional screenshot as a base64 PNG. Three limits are part of the product, not accidents. robots.txt is fetched and evaluated before the page is loaded, following RFC 9309 precedence, and a disallowed.
