docs(D.2b): chat-window re-drive design spec + list-ui-layouts research tool

Plan-2 chat piece of the LayoutDesc importer. Identifies the chat window as
LayoutDesc 0x21000006 (gmMainChatUI, element class 0x10000041) and grounds a
faithful, data-driven re-drive in the named retail decomp (ChatInterface +
gmMainChatUI + UIElement_Text/_Scrollable/_Scrollbar/_Menu) plus a user-provided
retail screenshot.

Design (full-faithful scope, user-approved):
- transcript = UIElement_Text 0x10000011 (dat font, bottom-pinned, 10k behead cap,
  pixel scroll, 1 line/wheel-notch)
- scrollbar = right-side track 0x10000012 + thumb 0x1000048c + up/down
- input = editable UIElement_Text 0x10000016 (caret, 100-entry history, Enter/Send)
- channel menu = UIElement_Menu 0x10000014 ("Chat" selector -> active channel)
- shared ChatCommandRouter extracted from ChatPanel
- screenshot correction: the four 0x10000522-525 left-edge elements are the
  numbered CHAT TABS (1-4), not scroll buttons (a research-agent inference the
  retail screenshot refutes)
- deferred (need non-UI plumbing, each gets a divergence row): tab switching/
  filtering, squelch, clickable name-tags, in-element word-wrap, styled runs,
  font config, opacity transition

Tooling: AcDream.Cli `list-ui-layouts <datdir> [0xRootType]` — read-only index of
every UI LayoutDesc by root element class + size + element-Type histogram; how the
chat layout was located (root type 0x10000041). Reusable for future panel re-drives.
