Connect SeleniumBase MCP and confirm it works

1. Run pip install "seleniumbase[mcp]" to get the seleniumbase-mcp command
2. Add {"command": "seleniumbase-mcp"} to your client's mcpServers (or claude mcp add seleniumbase-mcp -- uv run seleniumbase-mcp from a clone)
3. Call start_browser (optionally headless=true/false), then open_url

claude mcp add seleniumbase -- uvx seleniumbase

[mcp_servers.seleniumbase]
command = "uvx"
