Prepare plugin code for production

[TommyBez]

The plugin was refactored for production readiness, focusing on modularity, robustness, and performance.

• Architecture: The monolithic src/component.tsx was split into dedicated files:

  • src/types.ts: Centralized type definitions and constants.
  • src/utils/validation.ts: Encapsulates input validation logic.
  • src/utils/error-handling.ts: Provides custom error classes, a Logger, and DebouncedErrorHandler for structured, environment-aware logging.
  • src/utils/performance.ts: Contains useDebounce, useThrottle, MemoizationCache, and PerformanceMonitor for optimizations.
    This improves code organization, maintainability, and type safety, eliminating @ts-ignore comments.

• Error Handling & Validation: src/component.tsx now integrates src/utils/validation.ts for real-time input validation (duration, delay, iterations, custom properties) and sanitization, ensuring data integrity. Error scenarios are handled gracefully using the new error utilities.

• Performance: useDebounce was applied to configuration updates in src/component.tsx to prevent excessive re-renders. useMemo and useCallback were also introduced for memoized computations and stable callbacks.

• Accessibility: aria-label attributes were added to interactive UI elements in src/component.tsx to enhance screen reader support and keyboard navigation.

• Documentation: A comprehensive README.md was created, detailing features, architecture, and usage. A PRODUCTION_IMPROVEMENTS.md file was also added to summarize all changes made.
