libchev 1.1.1

Restore the shared debug console’s native WoW appearance with textured marble/rock panels, native borders, gold button labels, close button and scrollbar artwork. Every control remains privately owned and guarded.

Presented tests now show one final summary, including bounded-history and chat-fallback cases. Consumers can upgrade exact-revision embeds from 1.1.0 using scripts/vendor.py.

Validation: 87 Lua tests pass in normal/reverse order on Lua 5.1.5 and 5.2.4; all 24 vendor tests pass. GitHub CI is green. Texture templates were verified against installed Retail and Forever FrameXML; the visual change still needs an in-game check.
