Erik d1b13a7dbf test(D.2b): chat golden fixture + resolved-Type conformance (widget-generalization Task 1)
- Add ChatLayoutFixtureGenerator.cs (Skip-by-default) to regenerate
  chat_21000006.json from the live portal.dat via LayoutImporter.ImportInfos
- Commit generated fixture chat_21000006.json (13 KB, 400 lines) — dat-free,
  auto-copied to test output via existing *.json csproj glob
- Refactor FixtureLoader: extract shared LoadInfos(fileName) helper; add
  LoadChat() + LoadChatInfos() mirroring the vitals pattern; LoadVitalsInfos()
  now delegates to the shared loader (behavior unchanged, vitals tests green)
- Add ChatLayoutConformanceTests: ResolvesKnownElements + ResolvedTypes_MatchRetailRegistry

Confirmed resolved Types from live dat:
  0x10000011 (transcript) → Type 12 (style-prototype, skipped by factory)
  0x10000016 (input)      → Type 12 (style-prototype, skipped by factory)
  0x10000014 (menu)       → Type 6
  0x10000012 (scrollbar)  → Type 11
  0x10000019 (send)       → Type 1
  0x1000046F (max/min)    → Type 1

Also fix pre-existing build break: UiChatInput.MoveCaret(int delta) was made
private in ce848c1 but UiChatInputTests.Backspace_DeletesBeforeCaret called it
as public. Expose a public MoveCaret(int) overload (no-shift) alongside the
private MoveCaret(int,bool) — restores the intended test surface.

Full suite: 398 passed, 2 skipped (generator + pre-existing), 0 failed.
