GptMarkdownBlockEntrance class

Plays animation once, the first time this widget is built, then never again.

Deliberately one-shot and decided on first build: a streaming document rebuilds its tail constantly, and an entrance that re-armed on prop changes would restart every frame. A block that has already arrived stays arrived.

Honours the platform's reduced-motion setting, and renders statically when animation is GptMarkdownBlockAnimation.none — in that case no controller is created and no wrapper is added to the tree.
