renjianbo f2e65a8fbb feat: virtual company module, team projects, PWA dishes app, and startup scripts overhaul
- Add company module (3-tier org, CEO planning, parallel departments)
- Add company orchestrator, knowledge extractor, presets, scheduler
- Add company API endpoints, models, and frontend views
- Add 今天吃啥 PWA app (69 dishes, real images, offline support)
- Add team_projects output directory structure
- Add unified manage.ps1 for service lifecycle
- Add Windows startup guide v1.0
- Add TTS troubleshooting doc
- Update frontend (AgentChat UX overhaul, new views)
- Update backend (voice engine fix, multi-tenant, RBAC)
- Remove deprecated startup scripts and old docs

"""
性能测试:测量关键操作的响应时间和吞吐量。
测试指标:
1. 大规模数据构造 — 1000本书 + 3000张照片
2. 多孩子切换响应时间 — ≤300ms
3. 打卡操作响应时间 — ≤200ms
4. 积分查询响应时间 — ≤100ms
5. 照片列表查询 — 首屏 ≤1.5s
6. 读写混合场景 — 模拟家庭日常使用
运行方式:
python 14-test_performance.py
输出:
- 控制台打印测试结果
- 生成 15-test_report.md 报告
