feat: 第五轮开发 - 14项未来路线图功能完整实现

W1-W14 全部完成: - W1: 消息搜索 (ILIKE全文检索 + SearchModal) - W2: 对话导出 (JSON/Markdown/TXT三格式) - W3: 记忆时间线 DevTools 可视化 - W4: 通知推送系统 (WebSocket + Browser Notification API) - W5: 定时提醒 (30s轮询 + 重复提醒 + WebSocket推送) - W6: 每日简报 (08:00自动生成: 天气+新闻+提醒+AI摘要) - W7: IoT场景自动化 (规则引擎 10s轮询 + 条件评估 + 场景执行) - W8: 语音输入 (浏览器 Speech Recognition API) - W9: STT服务 (voice-service + whisper.cpp) - W10: TTS服务 (浏览器 Speech Synthesis + edge-tts三档回退) - W11: 文件管理 (上传/下载/缩略图/纯Go bilinear缩放) - W12: 知识库RAG (PostgreSQL tsvector + 文档分块 + 检索) - W13: 多模态 (图片上传+分析: Vision API + 本地Go分析回退) - W14: PWA (Service Worker + 离线页 + install prompt) 总计: 6个Go微服务 + 10+前端组件 + 10+ PostgreSQL表 + 4个后台调度器
