Add DOMContentLoaded, load, and readystatechange events with correct readyState transitions (loading→interactive→complete). Includes Window as a first-class event target, body onload spec quirk, and idempotency guards to prevent double-firing. Code review hardened the API surface by enforcing forward-only state transitions, eliminating a redundant wrapper function, and requesting a redraw after load handler DOM mutations.
