I want to add the "stagehand — Cursor Rules" prompt rules to my project. Repository: https://github.com/seyph/stagehand Please read the repo to find the rules/prompt file, then: 1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type) 2. If there's an existing rules file, merge the new rules in rather than overwriting 3. Confirm what was added
