Adds the TweenInfo datatype to the roblox standard library, matching Roblox's constructor and property surface: - TweenInfo.new(time?, easingStyle?, easingDirection?, repeatCount?, reverses?, delayTime?) - Properties: Time, EasingStyle, EasingDirection, RepeatCount, Reverses, DelayTime - Eq and tostring metamethods EasingStyle/EasingDirection arguments are validated against their Enum types. TweenInfo has no rbx_dom_weak backing (Roblox never stores it on instances), so it is a standalone datatype with no DOM conversion. Includes a Luau test and a changelog entry.

Summary
Adds the
TweenInfodatatype to therobloxstandard library. It was the only commonly-used tween-related datatype missing, soroblox.TweenInfocurrently returnsnil.What's included
TweenInfo.new(time?, easingStyle?, easingDirection?, repeatCount?, reverses?, delayTime?)with Roblox's defaults (Time = 1,EasingStyle = Quad,EasingDirection = Out,RepeatCount = 0,Reverses = false,DelayTime = 0).Time,EasingStyle,EasingDirection,RepeatCount,Reverses,DelayTime.EqandToStringmetamethods.EasingStyle/EasingDirectionarguments are validated against theirEnumtypes, mirroring howFontvalidatesFontWeight/FontStyle.Implementation notes
TweenInfois never stored on instances, so it has norbx_dom_weakbacking type. Like the enum singletons, it's therefore a standalone datatype and does not participate in DOM conversion (conversion.rs/extension.rs/attributes.rsare untouched). The two easing enums are stored asEnumItemrather than re-declared as Rust enums, keeping the surface small.Testing
