Feature/add auto mode settings and fix bug (#368)

* refactor: 将 convertMessagesToLangfuse 参数类型从 unknown 收窄为联合类型

将 readonly unknown[] 改为 readonly LangfuseInputMessage[]，
其中 LangfuseInputMessage = UserMessage | AssistantMessage | ChatCompletionMessageParam，
让调用方获得编译期类型检查。

* fix: 修复 Config 面板第二次进入时左右键无反应的问题

将左右键枚举值切换从依赖 DOM 焦点的 onKeyDown 改为 useKeybindings 系统，
确保按键在任何焦点状态下都能正确响应。同时修复 isSearchMode 初始值和布局问题。

* feat: 添加 RSS 内存指示器并解绑 auto 权限模式与 TRANSCRIPT_CLASSIFIER

- 在 REPL 底栏添加 RSS 内存使用显示，512MB 以下 dimColor，512MB-1GB warning 色，1GB 以上 error 色
- auto 权限模式不再依赖 TRANSCRIPT_CLASSIFIER feature flag，classifier 不可用时 fallback 到 prompting
- Config 面板 defaultPermissionMode 使用类型安全的 permissionModeFromString，显示改用 shortTitle
- bypassPermissions title 缩短为 Bypass 与 shortTitle 一致
