- 更新所有 handler 函数使用 updateFilters 替代 updateUrlParams - handleFilterChange - handlePageChange（移除 loadEvents 调用，由 useEffect 自动触发） - handleKeywordClick - handleRemoveFilterTag（移除 loadEvents 调用） - 重构 useEffect：监听 filters 状态替代 searchParams - 分离 Redux 数据加载到独立的 useEffect - 保持防抖逻辑（500ms） - 简化 useEffect 注释 适配新的状态管理模式，提升性能 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
