//! browser_close — Close the current session's browser page.
//!
//! Without this, pages persisted in the manager's HashMap forever. The
//! CDP session stayed open, the Chrome tab stayed visible on the user's
//! desktop, and a fresh agent invocation reused the stale page from a
//! prior task. The tool exposes `BrowserManager::close_page_for_session`
//! to the agent so it can clean up explicitly when a browser task is
//! complete.
