feat: 引入运行时日志体系和存储配置，配置文件改为必填

- 新增 pino/pino-pretty/pino-roll 依赖，实现结构化日志（console pretty + file JSONL rolling）
- 新增 Logger 接口及 PinoLoggerWrapper/ConsoleFallbackLogger/NoopLogger/MemoryLogger 实现
- 新增 src/pino-roll.d.ts 类型声明
- 新增 server.storage.dataDir 配置（默认 ./data，相对路径基于配置文件目录）
- 新增 server.logging 配置（level/console/file/rotation，支持变量引用）
- 配置文件从可选改为必填，parseRuntimeArgs 无参数时抛错
- bootstrap 创建 logger、确保 dataDir、shutdown flush、失败路径 fallback
- startServer 接收 logger 并输出结构化监听日志
- ESLint 新增 no-restricted-syntax 禁止 src/server 直接 console.*（排除 logger.ts）
- 更新 config.example.yaml、README.md、DEVELOPMENT.md 同步配置和日志文档
- 完善测试覆盖：logger、config、schema、bootstrap 共 150 个测试通过
