feat(chat): Campaign CH slice CH2 — retail SpewBox interface text

Retail routes on-screen refusals ("You can't jump while in the air",
"You are too encumbered to carry that!") through a SEPARATE transient
screen surface (gmSpewBoxUI, ClientSystem::AddTextToScroll @0x00563C50)
that never touches the chat scroll — type 0x1A is exactly the bit every
ChatInterface window's default filter excludes
(ChatInterface::ChatInterface @0x004F4550). acdream had no such split:
every WeenieError rendered in chat at a single stand-in LogTextType
0x00 (CH1-era approximation, register AP-176), and locally-detected
jump refusals were silently discarded.

This slice ports the full mechanism per
docs/research/2026-08-09-chat-retail-interface-text.md:

CORE (AcDream.Core/Chat):
- WeenieErrorMessages.Resolve now returns (text, RetailLogTextType) from
  a 338-row transcription of ClientCommunicationSystem::HandleFailureEvent
  @0x00571990 (Appendix A's 339 cases minus one, 0x4F8, deliberately
  excluded — its case body is a tangled decompiler artifact, not
  resolvable with confidence). Spot-checked ~20 rows directly against
  the raw decomp (case 0x2b/0x36/0x3a/0x4e/0x4ec/0x4f3/0x4f4 and the
  jump family), beyond the ~10 the brief asked for, because the first
  pass surfaced two transcription classes the research doc's markdown
  silently ate: (1) 7 ids marked "shared string global" resolved by
  reading the case bodies directly (0x24/0x48/0x49 reuse the jump-
  refusal globals; 0x4DE/0x4DF/0x55A/0x55E are pure param passthrough);
  (2) 19 "arg3 + literal" CONCATENATION ids whose leading space (and
  therefore their %s marker) the markdown table's cell-trimming ate —
  fixed by re-reading each case body, several requiring a SECOND
  non-truncated data_XXXXXXXX dump elsewhere in the same oracle file to
  recover text the ~33-char inline preview cut off. One retail typo is
  preserved verbatim: 0x4F4's second placeholder is literal "$s", not
  "%s" — only the first substitutes.
- ClientTextRefusals: the 11 process-lifetime string globals, all
  byte-recovered from the PDB-paired C:\Users\erikn\Downloads\acclient.exe
  (MATCH verified via check_exe_pdb.py) via raw UTF-16LE prefix search —
  5 were truncated in the research doc's own transcription and all 5
  turned out to end "...combat mode"/"...this position", not the
  shorter "...combat" a truncated read would suggest.
- SpewBoxState: the gmSpewBoxUI pending/visible queue port (insert-at-0,
  dedupe-against-index-0-only, MaxConcurrentItems overflow, per-entry
  expiry, one-frame enqueue/drain decoupling). Placed in Core (not
  Runtime as the brief's default) because AcDream.UI.Abstractions
  references Core but not Runtime, and SpewBoxVM needs to wrap it
  directly — the same constraint ChatVM already satisfies against
  ChatLog.
- Folded the 4-entry WeenieErrorText.cs into the full table; deleted it.

RUNTIME (AcDream.Runtime):
- RuntimeCommunicationState.AddText(text, type, windowId): the
  AddTextToScroll chokepoint. type == ClientLocal -> SpewBox only, never
  chat; everything else -> the existing transcript, tagged with type.
- GameEventWiring gains an `onInterfaceText` delegate hole (Core.Net
  cannot reference Runtime, so this follows the file's own established
  pattern for every other Runtime-owned sink). Rewires 0x028A/0x028B/
  UseDone through the full table + router; fixes 0x02EB
  CommunicationTransientString's routing type from a CH1-era 0x00
  guess to retail's hardcoded ClientLocal (Handle_Communication__
  TransientString @0x0057D460).
- LiveSessionEventRouter's 0xF7E0 ServerMessage handler now routes
  through AddText with the wire chatType verbatim instead of always
  writing ChatLog directly.
- PlayerMovementController gains OnInterfaceText, applied by
  RuntimeLocalPlayerMovementState to every controller it installs.
  Reports ChargeJump/jump refusals exactly as ClientCombatSystem::
  CommenceJump @0x0056AF90 / DoJump @0x0056B110 do — confirmed via
  their compiled dispatch that ONLY 0x24/0x48/0x49 produce text;
  0x47 (GeneralMovementFailure, fully-constrained/no-stamina) and any
  other code are retail-SILENT (DoJump's jump table has exactly 4 real
  targets), which contradicts this task's brief ("0x47 -> the
  constrained/stamina row per §4.2") — the brief's reading of §4.2
  described what jump_is_allowed COMPUTES, not what CommenceJump/DoJump
  DISPLAY for it. Implemented the decomp-verified silent behavior.

APP (AcDream.App / AcDream.UI.Abstractions):
- The 5 composition sites that already used RetailLogTextType.ClientLocal
  now call Communication.AddText instead of Chat.OnSystemMessage
  directly, so they reach the SpewBox instead of the transcript.
- SpewBoxVM (UI.Abstractions) + SpewBoxController (App), modeled
  directly on PortalWaitNoticeController. Position/font/colour/
  MaxConcurrentItems are placeholders: SpewBoxLayoutDumpDiagnostic
  exhaustively swept the installed client_portal.dat's entire LayoutDesc
  id range (0x21000000-0x21000075, 101/118 ids populated, sanity-checked
  against 3 known ids) and found ZERO elements of class 0x10000016 —
  gmSpewBoxUI is mounted from C++ code, not any authored LayoutDesc, so
  the dump cannot recover these values.

REGISTER: AP-176 retired (its WeenieError half is now the full table
port); its OnCombatLine half was never in this slice's scope and is
split out to AP-179 so that divergence keeps a row. AP-177 (invented
line lifetime) and AP-178 (invented position/font/colour/max-items)
filed for the presentation placeholders above. AP-175 (PopUpString ->
chat instead of modal) is untouched, not duplicated.

Suite: 11,890 passed / 4 skipped / 0 failed (was 11,835/4/0; +55 net
new tests, 0 regressions).
