Stage 9.5b3b: component, settings and CLI reference (D292)

core/curve with presets, keys, wraps; KindCurve in schema, scenes, prefabs and the inspector curve editor.
modules/tween: tweens and timers in per-world pools, game and unscaled domains, script field targets via contracts/scriptfields.
Host handle types (abi.Handle, bind.Handle, manifest v5), yield on awaitable handles via contracts/scriptwait.
Script modules aego/curve, aego/tween, aego/timer; platformer enemy uses a cooldown and a fade-out tween.
Docs: tween.md, curves.md, language reference; golden for the curve editor.
