Updatable (Removed)

The Updatable interface has been removed. Systems are now plain classes that provide update(UpdateContext&) and are wrapped by the type-erased System class internally.

Migration

Before	After
class MySystem : public System	class MySystem (plain class)
void update(UpdateContext&) noexcept override	void update(UpdateContext&) noexcept
void init(GameWorld&) noexcept override	void init(GameWorld&) (optional, detected via concept)
gameWorld_->view<...>()	ctx.view<...>()
