docs(D.2b): spec correction — input is Variant B, Type 3 not registered

Record the two execution-time corrections to the design's registration
assumptions: the editable input resolves to Type 12 (Variant B, controller-placed
UiField), and Type 3 is NOT factory-registered (acdream's Type-3 elements are
chrome/containers, kept on the UiDatElement fallback).

> **Implementation correction (2026-06-16, settled during execution).** Two of
> this design's registration assumptions changed once the empirical resolved
> Types were in hand (Task 1):
> 1. **The editable input `0x10000016` resolves to Type 12 (Text), not Type 3.**
> So the input is **Variant B** — the factory builds it as a `UiText`
> placeholder and `ChatWindowController` removes that and controller-places a
> `UiField` at its rect. (Confirmed by the chat golden fixture.)
> 2. **Type 3 is NOT registered → `UiField` in this pass.** In acdream's vitals
> (`0x2100006C`) and chat (`0x21000006`) layouts, Type-3 dat elements are
> sprite-bearing **chrome** (the 8-piece bevel corners/edges, e.g. vitals
> `0x10000633` → sprite `0x060074C3`) and the transcript/input **container**
> panels — NOT editable fields. Retail draws those as inert media-bearing
> Fields, which our generic `UiDatElement` reproduces pixel-for-pixel and
> without a spurious focus/edit affordance. Registering Type 3 → `UiField`
> (which draws no dat sprite) would blank the vitals bevel. So the factory
> switch registers **Button (1), Menu (6), Meter (7), Scrollbar (11), Text
> (12)**; Type 3 stays on the `UiDatElement` fallback. `UiField` still ships
> (the renamed editable widget) — it is just controller-placed, not
> factory-wired. Register Type 3 → `UiField` only when a window carries a
> factory-built editable Type-3 field (and `UiField` then grows a
> background-media draw + an opt-in editable flag). Guarded by
> `VitalsTree_ChromeCornerHasExpectedSprite` (asserts the corner stays a
> `UiDatElement` drawing its sprite).
