新增活跃度查询工具

功能： - 查询指定时间范围内的活跃节点数和活跃人数 - 活跃节点：统计 nodeinfo 表 updated_at 字段 - 活跃人数：统计 text_message 表按 from_id 去重的用户数使用场景： - 用户问'现在有多少人活跃'时 AI 调用此工具 - 用户问'当前有多少节点在线'时 AI 调用此工具 - 支持附带时间条件，默认1小时，最大24小时参数： - hours: 查询最近N小时，默认1小时，最大24小时 - query_type: both/nodes/users，默认 both 实现： - internal/agents/active/active.go - 工具主逻辑 - internal/store/active_store.go - 数据库查询方法 - 完整的单元测试，所有测试通过 - 在 ai/service.go 中注册工具测试： - ✅ 默认查询（1小时，both） - ✅ 指定时间查询（6小时、24小时） - ✅ 仅查询节点/人数 - ✅ 时间限制验证 - ✅ 项目编译成功 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
