Smoke Test

This automates the full cycle of spinning up a new Mastra project and verifying the studio actually works in a real browser. It runs create-mastra with your chosen version tag and package manager, sets up a browser-enabled agent with Stagehand, then uses Chrome MCP to click through the UI and test agent chat responses. The validation is thorough: it checks that agents load, the chat interface works, and even sends test messages to verify the LLM integration. Most useful when you're testing a new Mastra release or need to verify a clean install works before recommending it to your team. Saves you from manually clicking through the same UI checks every time.
