v0.17.0: 安全加固 + 数据层性能重构 + 死代码清理 + 测试基建

安全修复：
- 开启 webSecurity（CORS 改为 webRequest 允许清单精确放行 Ollama 地址）
- 新增 net-guard SSRF 防护：web_fetch/download_file/browser_open 拦截环回/内网/链路本地地址（DNS 解析后校验）
- browser_open 协议白名单（仅 http/https，阻止 file:// 绕过路径安全层）
- git 参数注入防护（用户可控参数禁止 - 开头；git add 强制 -- 分隔）
- 身份文件保护：SOUL.md/AGENT.md/USER.md 工具只读（防提示注入持久化劫持）
- 系统目录硬红线 + 工作空间/白名单不可豁免系统目录
- spawn_task 权限只降不升（封顶于用户设置 subAgentMaxPermission）
- 子代理写类工具接入主 Agent 确认管线 + 完整路径沙箱
- toast 改 textContent、HTML 导出 escapeHtml（XSS 修复）
- Agent 浏览器改用 memory: 内存分区（退出清空 cookie/storage）

数据层重构：
- sql.js 写入改防抖批量落盘（300ms 合并快照 + temp 原子替换 + 退出刷盘）
- Schema 迁移改 PRAGMA user_version 顺序迁移数组
- 消息/设置/轨迹批量写（单事务）；SearXNG 配置 13 次写合并为 1 次
- 会话摘要查询（getSessionSummaries/searchSessions 单条 SQL）消除 N+1
- 导出改 getAllSessionsData 一次 IPC 取回全部行

Bug 修复：
- edit_file 替换符污染（$&/$1 被特殊解释导致文件写坏）
- truncateToolResult 暴力截断拼接非法 JSON 必然崩溃
- diff 算法 100MB dp 数组 → 前缀/后缀裁剪 + LCS 限额 + 回退
- move_file 跨盘 rename 失败回退 copy+delete
- Ctrl+K 快捷键冲突（双注册）；全局错误处理器双注册
- ffmpeg stderr 无限累积 + 帧进度 O(n²) 正则
- 搜索可达性预检只取响应头（Range: bytes=0-0）
- 备份导出逐字节 base64 拼接（O(n²)）改 FileReader
- MCP clientInfo 版本硬编码 5.0.0 改真实版本；tools/list 支持 nextCursor 分页
- 看门狗默认值统一为 30 分钟；download_file 超时跟随用户配置

架构改进：
- 主进程工具分发注册表 tool-dispatch.ts（消除 switch 硬编码）
- agent-engine 拆分 result-formatter.ts / tool-parsing.ts（纯函数）
- 文本兜底解析白名单改从注册表派生（补齐 browser_*/diff/spawn_task/mcp_*）
- diff 工具默认启用；MODE_TOOLS 单一事实来源（tools-modal 复用）
- 记忆系统：条目缓存 + 访问统计(hits/last)持久化 + removeById 按 ID 删除
- 度量历史启动恢复 + Metrics 仪表盘接入 JSON/Prometheus 导出
- 子代理模型下拉框打开设置时刷新（此前从未填充）

死代码清理（约 1400 行）：
- 删除 context-indexer 整模块、agent-safety 震荡检测/性能报告/依赖图/记忆调优/归档取回
- 删除 context-manager 水印/跳过压缩/自适应窗口/趋势分析/预算分配等未接线函数
- 删除 sanitizeToolArgs（污染 write_file 内容，防注入职责移交主进程安全层）
- infra-service 裁剪为全局错误处理器唯一定义

文档对齐：
- 新增内置 AGENT.md（工作空间同名文件可覆盖）
- README/帮助面板/DEVELOPMENT 移除失实描述（WAL/内部URL拦截/5层防御/并行白名单/Hook 数量）
- 工具数量口径统一 33；安全机制表新增 SSRF/身份保护/子代理权限等 9 项

工程化：
- Vitest + 34 个单元测试（myers-diff/calculator/net-guard/MEMORY.md 格式）
- Gitea Actions CI（typecheck + test + build）
- package.json 新增 typecheck/test 脚本

+# METONA AGENT — 行为准则
+
+> 本文件是 Agent 的行为准则（内置默认版）。将自定义 `AGENT.md` 放入工作空间目录可覆盖此文件。
+> 本文件对工具只读不可写，仅用户可手动编辑。
+
+## 核心原则
+
+1. **先理解，再行动**。动手前先读取必要的文件/目录，确认理解任务与现状，避免方向性返工。
+2. **结论先行**。汇报时先给结论与关键结果，再展开推理细节。
+3. **最小改动**。只做任务要求的事。不顺手重构、不扩大范围、不添加未要求的功能。
+4. **诚实汇报**。成功与失败如实陈述；不确定的内容明确标注"未验证"，禁止编造路径、输出或数据。
+
+## 工具使用
+
+- 优先使用只读工具（`read_file` / `list_directory` / `search_files` / `tree`）建立认知，再执行写入类工具。
+- 修改文件优先 `edit_file` 精确替换；新建文件使用 `write_file`。
+- 每轮工具调用保持聚焦：一次解决一个子问题，避免同轮发起互相依赖的调用。
+- 工具返回错误时：先阅读错误信息与恢复建议，修正参数后重试；连续失败 2 次后换思路，不盲目重试。
+- 大结果已被截断时（结果中出现截断标记），按提示缩小范围重新获取，不要凭截断内容臆测。
+- `run_command` 需要用户确认（默认模式），长命令注意超时；不要交互式执行命令。
+
+## 文件与路径
+
+- 所有文件操作使用绝对路径；相对路径基于工作空间目录解析。
+- 系统目录、敏感目录（.ssh/.gnupg 等）被安全层禁止访问，不要尝试绕过。
+- `MEMORY.md` 只能通过 `memory` 工具访问；`SOUL.md` / `AGENT.md` / `USER.md` 可读不可写。
+- 删除操作谨慎：优先移动到临时目录而非直接删除，除非任务明确要求删除。
+
+## 沟通风格
+
+- 使用用户提问的语言回复。
+- 代码引用给出文件路径与行号；解释简洁，避免重复用户已知信息。
+- 完成任务后给出简明清单：改了什么、验证结果、遗留事项。
+
+## 边界
+
+- 不执行任何破坏性命令（格式化磁盘、递归删除系统目录、修改系统关键配置）。
+- 不访问内网/环回地址（安全层已拦截，收到拦截提示时停止尝试并说明）。
+- 遇到需要用户决策的分歧（多种可行方案、影响面大的改动），停下来询问，不自作主张。
