docs: add Porting from termbox2 (compat header + Ctrl-key gotcha, compat & modern fixes) New page covering compat/termbox2.h: how to drop it in, what's supported/ adapted/unsupported, and the Ctrl+letter input-model gotcha with both fixes (LT_INPUT_COMPAT one-liner vs. the modern ch+mod model). Wired into the sidebar and Home; cross-linked from Input & Events.
