feat(vis): add session download, import, export and delete

 - Core: Fix HTTP header values containing trailing whitespace/newlines on certain Linux systems (e.g. kernel 6.8.0-101) causing connection errors — strip whitespace from ASCII header values before sending
 - Core: Fix OpenAI Responses provider sending implicit `reasoning.effort=null` which breaks Responses-compatible endpoints that require reasoning — reasoning parameters are now omitted unless explicitly set
+- Vis: Add session download, import, export and delete — one-click ZIP download from session explorer and detail page, ZIP import into a dedicated `~/.kimi/imported_sessions/` directory with "Imported" filter toggle, `kimi export <session_id>` CLI command, and delete support for imported sessions with AlertDialog confirmation
 - Core: Fix context compaction failing when conversation contains media parts (images, audio, video) — switch from blacklist filtering (exclude `ThinkPart`) to whitelist filtering (only keep `TextPart`) to prevent unsupported content types from being sent to the compaction API
 - Web: Fix `@` file mention index not refreshing after switching sessions or when workspace files change — reset index on session switch, auto-refresh after 30s staleness, and support path-prefix search beyond the 500-file limit

 - Core：修复部分 Linux 系统（如内核版本 6.8.0-101）上 HTTP 请求头包含尾部空白/换行符导致连接错误的问题——发送前对 ASCII 请求头值执行空白裁剪
 - Core：修复 OpenAI Responses provider 隐式发送 `reasoning.effort=null` 导致需要推理的 Responses 兼容端点报错的问题——现在仅在显式设置时才发送推理参数
+- Vis：新增会话下载、导入、导出与删除功能——在会话浏览器和详情页支持一键 ZIP 下载，支持将 ZIP 文件导入到独立的 `~/.kimi/imported_sessions/` 目录并通过"Imported"筛选器切换查看，新增 `kimi export <session_id>` CLI 命令，支持删除导入的会话并提供 AlertDialog 二次确认
 - Core：修复对话包含媒体内容（图片、音频、视频）时上下文压缩失败的问题——将过滤策略从黑名单（排除 `ThinkPart`）改为白名单（仅保留 `TextPart`），防止不支持的内容类型被发送到压缩 API
 - Web：修复 `@` 文件提及索引在切换会话或工作区文件变更后不刷新的问题——切换会话时重置索引，30 秒过期自动刷新，输入路径前缀可查找超出 500 文件上限的文件
