/**
 * ConfirmationDialog — 工具执行确认对话框（v0.3.2 批量审批版本）
 *
 * 当 Agent 并行调用多个 requiresPermission=true 或 riskLevel>=HIGH 的工具时，
 * 通过此对话框批量请求用户确认。
 *
 * v0.3.2 关键改进：
 * 1. state 从单值改为数组，支持同时显示多个 pending 请求
 * 2. 弹框打开时主动调用 getPendingConfirmations 拉取已积压请求，
 *    解决并行 IPC 事件在前端 state 中互相覆盖丢失的问题
 * 3. 同工具多次调用按 toolName 分组展示（如 read_file (×5)）
 * 4. 支持批量勾选 / 批量批准 / 批量拒绝
 * 5. remember/autoExecute 按 toolName 去重应用到所有选中项
 *
 * 监听 IPC 事件 `tool:confirmationRequest`，显示工具详情，
 * 用户确认/拒绝后通过 `tool:confirmationResponseBatch` IPC 通道批量发送结果。
