auto_shimmer_animate

Introduced the loadingBuilder parameter to allow for manual loading UI while bypassing automatic skeleton generation. Refined default visual constants for a more subtle shimmer effect and improved color configuration handling.

• Added loadingBuilder to AutoShimmerAnimate to support custom loading widgets that still benefit from the shimmer animation.
• Updated default highlight color to a soft light grey (0xFFFAFAFA) and reduced default highlight width to 0.08.
• Modified ShimmerWrapper to ensure highlightColor and highlightOpacity are applied even when animation overrides are not present.
• Enhanced AutoShimmerAnimate logic to prioritize loadingBuilder over auto-generated skeletons.
• Expanded README.md with detailed usage examples for layered skeletons, custom loading UI, and parameter tables.
• Added comprehensive unit tests for loadingBuilder logic, shimmer builder wrapping, and color override persistence.
• Updated CHANGELOG.md to reflect version 0.1.1 changes.

Introduced a synchronized animation system that allows individual skeleton elements to animate in unison while maintaining their own clipping bounds. This improves the visual quality of layered skeletons, specifically for nested widgets like Cards and Containers.

• Introduced AutoShimmerScope to provide a shared animation controller and coordinate shader bounds across a widget subtree.
• Added perElementShimmer, highlightOpacity, and highlightWidth to AutoShimmerConfig to allow fine-grained control over the shimmer highlight.
• Updated SkeletonBox to optionally host its own AutoShimmerEffect, enabling per-widget animation masks.
• Refactored CardAdapter and ContainerTransformer to use a stacked rendering approach, ensuring parent surfaces and child content maintain distinct skeleton layers.
• Refined default visual constants, including updated colors in AutoShimmerColors and a shorter 1600ms default animation duration.
• Introduced AutoShimmerGradient to centralize shimmer logic, including support for sliding transforms and adjustable highlight widths.
• Updated AutoShimmerEffect to use BlendMode.srcATop and support external animation objects from AutoShimmerScope.
• Expanded documentation in README.md with default value tables and tuning examples.
• Added comprehensive tests for synchronized animations, localized shader bounds, and configuration defaults.

Replaced the shimmer_animation third-party dependency with a custom, internal animation engine to improve package independence and maintainability.

• Introduced AutoShimmerEffect, a built-in animation engine utilizing ShaderMask and LinearGradient.
• Added AutoShimmerDirection enum to replace external shimmer direction types.
• Added repeatDelay support to AutoShimmerAnimate, AutoShimmerConfig, and related builders to control timing between animation loops.
• Deprecated the interval property in favor of repeatDelay for better naming consistency.
• Updated ShimmerWrapper to use the new internal AutoShimmerEffect instead of the external Shimmer widget.
• Updated unit tests to verify AutoShimmerEffect behavior, including repeatDelay and disabled states.
• Updated documentation and examples to reflect the new API changes and internal engine.
• Bumped package version to 0.0.2.

Updated the README with badges, streamlined documentation, and simplified code examples. Corrected the repository, homepage, and issue tracker links in pubspec.yaml.

• Refactor README for conciseness and add pub.dev badges.
• Convert API overview to a table format.
• Simplify usage examples and remove redundant sections.
• Update project URLs in pubspec.yaml to match the repository name.
