An editable input is the first element that exercises the complete interactive architecture rather than only one layer. It must become focusable when attached, receive key events through the focused dispatch path, maintain semantic editing state, participate in layout, request frames through Host mutations, and emit typed changes to raw or framework consumers. Building it from the APIs already introduced demonstrates that interactive elements can be authored as composable extensions instead of privileged core cases.

Editing behavior lives in InputApi, independent of any particular framework. The model uses code-point positions rather than UTF-16 code units, normalizes pasted line breaks for a single-line control, and keeps key-repeat behavior input-specific. Emitting input only when the value changes gives every adapter the same predictable onInput semantics.

host.addEventListener(input, 'input', (event) => {
	console.log(event.value);
});

This PR adds the typed input element and semantic insert, delete, and caret movement operations. It composes focus, keyboard handling, layout, and typed input events while exposing the current value and caret through element properties. Tests cover editing boundaries, multi-code-unit characters, key mappings, repeats, delegation, and event emission.
