DX-3089, DX-3107: Browser Use on Box: connect page section and scheduled agent guide - #879

Summary

Two Browser Use additions to the Box docs.

Connect over CDP page (DX-3089)

• Adds a "Browser Use" section to box/overall/browser/connect.mdx, next to Stagehand, showing a Browser Use agent driving the box browser from your own machine over the CDP URL.
• Names Browser Use in the page intro and in the "Connect over CDP" card on the browser overview page.

Scheduled Browser Use Agent guide (DX-3107)

• Adds box/guides/browser-use.mdx: Browser Use runs inside a box, launches the box's Chromium itself, writes a markdown report to reports/, and runs daily through box.schedule.exec. agent.py exits with an error if the agent does not finish the task; setup.py raises if a box command fails; reports.py re-attaches and prints the reports.
• Added to the Guides nav after "Playwright Web Scraping".

Testing

Run against real boxes with browser-use 0.13.10 and upstash-box 0.3.0:

• Connect snippet (asyncio.run(agent.run()) shape): returned the install command from the quickstart page; a multi-step click task completed; the tab was visible through box.browser.list_tabs().
• Guide, copied from the MDX into a fresh folder: setup.py finished in 208s with a report in front-page order, reports.py printed it, the daily schedule was created. A scheduled run on a paused box auto-resumed the box and completed.
• Agent runs take 3.5–4.5 minutes, which needed upstash/box-backend#280 (exec timeout raised from 5 minutes to 1 hour); merged and verified on the deployed backend.
• Both MDX files compile; previewed with docs7 dev.

The connect snippet uses claude-sonnet-4-5 because browser-use 0.13.10 sends a forced tool_choice that claude-sonnet-5-5 rejects unless a thinking option is passed.
