refactor: remove type assertions in component props

- create proper UncapStarProps and TranscendenceStarProps interfaces
- use discriminated union for StarRender type
- add function overloads for createStarProps with type safety
- remove 'as any' casts from star component spreading
- remove optionalProps workaround in SegmentedControl
- stop spreading HTMLAttributes to RadioGroupPrimitive (not supported)
