Release 1.1.2 — the default path works end to end

Fix release for 1.1.1: the minimal path end to end, engine commands that
run on Godot, Unity and Unreal, hook warnings you can see, and verdicts
that say when they could not check. Details in CHANGELOG.md; upgrade
steps in UPGRADING.md (v1.1.1 → v1.1.2).

Fixes #67
Fixes #131

+#### Section F2: Input Method Completeness Checklist
+
+One checklist block per input method in the spec's **Platform Target** line —
+keyboard, gamepad, mouse, touch; drop the blocks for methods this game does not
+support and say so. Take the items from section 11 of
+`.claude/docs/templates/ux-spec.md` (reachability, tab/d-pad order, visible
+focus, focus trap for modals, Esc/back behavior, hit-target sizes, controller
+disconnect). Tick an item only when the Interaction Map above already specifies
+it; an unticked item is an open implementation question — list it under Open
+Questions rather than ticking it.
