- Added comprehensive state management with conditional states, priority-based resolution, and property overrides

- Added responsive.lua with fluent builder API (:when()/:apply()/:otherwise()) for creating responsive layouts that react to parent size or custom conditions
- All elements now use getResolved() to check active states, enabling multiple responsive rules to coexist
