v0.0.11: Accessibility and performance improvements

Accessibility Enhancements: - Added role="alert" to error messages and read-only notices for screen readers - Improved semantic HTML for better assistive technology support Performance Optimizations: - Implemented debounced search (300ms) to reduce re-renders during typing - Added pagination support for large datasets (configurable limit up to 1000) - Enhanced server-side data fetching with query parameter support Input Improvements: - Changed rollout percentage validation from parseInt to parseFloat for better decimal handling - Made admin URL construction configurable using config.routes.admin - Improved input validation with proper rounding for percentage values Developer Experience: - Added reusable useDebounce hook for performance optimization - Better error handling for edge cases in numeric inputs - Cleaner code organization with separated concerns 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
