/**
 * Minimal `run`-cell JavaScript runtime for the browser tool.
 *
 * Ported from oh-my-pi's shared `JsRuntime` (eval/js/shared/runtime) reduced to
 * the browser-relevant surface: an async function body executed with `page`,
 * `browser`, `tab`, `display`, `print`, `assert`, `wait`, `sleep`, and
 * `console`. Oh-my-pi-specific helpers (read/write/tree/env/tool/agent/
 * parallel/pipeline/phase) are deliberately not provided; calling them yields a
 * clear ToolError instead of a ReferenceError.
