test(shimmer): Add comprehensive test suite

Add 34 tests covering shimmer animation components:
- ShimmerState: creation, duration, looping, progress, reset
- SkeletonLoader: creation, widths, effect, colors
- Spinner: creation, style, label, color, frames
- ProgressBar: creation, clamp, label, show_percent, chars
- TypingIndicator: creation, label
- Countdown: creation, label, remaining
- LoadingState: is_loading, is_complete, is_error
- LoadingOverlay: creation, show, show_progress, hide, complete, error
- blend_colors: RGB blending, non-RGB fallback

Note: Tests cannot be run due to pre-existing compilation errors
in views.rs which has API mismatches with other modules.
