fix: 全面修复审计问题并优化系统提示词
**崩溃/挂死修复 (5):** - 统一 TrayManager.isQuitting 变量,修复 Cmd+Q 无法退出 - useAgentStream 闭包过期快照 → 每次 getState() - Agnes chatStream 添加 AbortSignal.timeout - SSE JSON.parse 添加 try-catch 保护 - Orchestrator setTools 污染 → save/restore 模式 **功能修复 (14):** - 上下文压缩实现 (每5轮 COMPRESSING 状态) - 修复 requestId 硬编码空串 - ConfigService.set() 保留已有 category - MemoryManager 新增 working 类型搜索 - PromptInjectionDefender 补全 sanitize() - Ollama: 补全 dynamicReminders + reasoningContent - openai-format: 所有 assistant 消息保留 reasoningContent - SSE: finish_reason 时提前 flush tool_calls - DeepSeek thinking effort 映射注释 - Ollama done_reason load→stop - RateLimitHook >= 边界修复 - WorkspaceService isValid 首次启动修复 - sessions:archive IPC handler - 托盘/窗口图标路径生产环境修复 **系统提示词优化:** - SOUL.md 存在时不显示兜底身份,原文放最前 - 兜底身份改为中文 (MetonaAI 自身描述) - 用户文本在前,附件内容在后 **文件上传:** - 非图片文件不再 base64 编码,保留 JSON 结构 - 用户文本优先于文件内容 **UI 修复:** - 首页 Logo 路径修复 (public/ + 相对路径) - TokenUsage contextWindow 动态计算 (Provider 感知) - 切换 Provider 同步 contextWindow - 托盘图标始终显示 Logo (状态由右键菜单展示)
