feat: v0.10.0 生产环境优化 — HTTPS、前端生产构建、安全加固

- feat(deploy): 前端多阶段构建 (vite build + nginx:alpine)，移除 Vite 开发模式
- feat(deploy): OpenResty HTTPS 配置 (SSL + HSTS + 安全头)
- fix(ws): WebSocket 路由添加 /api 前缀，修正前后端路径不匹配
- security: SSH AutoAddPolicy → WarningPolicy
- security: CORS 来源环境变量化 (CORS_ORIGINS)
- security: 限流器使用 X-Forwarded-For 真实客户端 IP
- perf(db): 数据库连接池配置 (pool_size=20, max_overflow=40)
- refactor: 移除硬编码 URL/IP (NTP、域名、微信代理)，改为环境变量
- chore: 更新 .env.example 模板，补充新增配置项
- chore: 清理 .reasonix/、scripts/、guide.md 无用文件
- docs: 更新 CLAUDE.md 至 v0.10.0，补充生产架构文档
