v0.17.1: 退出释放显存修正 + 备份完整性 + 核心逻辑测试补课 + 上下文逻辑收敛 + 记忆日志可读性

修复： - main.ts 退出释放模型显存改用 getSetting(serverUrl)，不再硬编码 127.0.0.1:11434（避免非默认地址时释放请求打到错误端口） - 备份导出/导入并入 localStorage 持久化状态（会话摘要、度量历史、轨迹降级缓存、主题），版本升级到 v2，实现完整备份 - 工具数量改为 getEnabledToolDefinitions().length 动态计算，删除写死"32 个"的硬编码 - 记忆日志区分操作来源：memory:write 透传 reason，标注"新增记忆/替换/删除/清空/TTL 衰减清理/访问统计写回（无新条目）"，避免"写了但看不到新记忆"的困惑可维护性： - 上下文压力逻辑收敛到统一 calculateContextStats，删除 getContextPressureLevel / getTrendAwareCompressThreshold 的重复实现 - 消除 validateToolArgs 同名碰撞（agent-engine 本地版改名 validateToolArgsQuick） - 子代理工具集改用 getEnabledToolDefinitions() 基线，跟随全局启用开关与 Plan 模式 - 抽取 html-utils.ts 纯函数模块（实体解码/HTML→文本/HTML→Markdown/拦截页检测/相关性评分），tool-handlers-system 净减约 190 行重复代码 - 统一静态导入（savePlanTracker/setPlanModeActive/collectDiagnostics/addWrittenFile） - console.* 使用处补充豁免说明（启动/退出/刷盘阶段无渲染进程可推送日志） - run_command 工具描述改为反映可配置执行模式测试： - 新增 7 个测试文件 + 扩展 2 个，共 273 个测试（原 34 → 273） - 覆盖 agent-engine / agent-safety / context-manager / tool-registry / result-formatter / tool-parsing / memory-service / crypto / build-context / html-utils / utils / tool-handlers-fs - 全部通过 npm run typecheck && npm test && npm run build
