Summary of Changes

Hello @zhukeev, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on enhancing the performance and developer experience of the "spoiler_widget" package. A new "updateInterval" property has been added to "ParticleConfig", enabling developers to throttle particle updates and improve rendering efficiency. Alongside this, comprehensive contributing guidelines and release check scripts have been introduced to foster easier contributions. The changes are supported by updated documentation and a new example page dedicated to performance tuning.

Highlights

• Particle Update Throttling: Introduced "ParticleConfig.updateInterval" to control the frequency of particle updates, allowing for performance optimization by reducing unnecessary redraws.
• Improved Developer Experience: Added a "CONTRIBUTING.md" guide and "release_check.sh" scripts to streamline the contribution process and automate release verification.
• Enhanced Documentation: Expanded the documentation for "ParticleConfig" properties, including the newly added "updateInterval", to provide clearer guidance.
• Performance Tuning Example: Included a new "SpoilerPerformancePage" in the example application, allowing users to interactively test and tune particle performance settings.

Code Review

This pull request introduces an updateInterval for particles to improve performance by throttling updates. The implementation correctly uses a time-based delta for animations, making them framerate-independent. The changes include adding a new performance demo page, tests for the new feature, and developer experience improvements like contribution guidelines and release scripts. The code is well-structured, and I've included a few suggestions for improving maintainability by removing magic numbers and a minor correction for the example app and changelog.
