dsh-client-ui-history-nav

Browser-style Back / Forward / Refresh controls in the DSH client window title bar. Sessions and plugin panels share one history stack, and a refresh asks for confirmation while a session is still running.

给 DSH 客户端加浏览器式「后退 / 前进 / 刷新」：会话与插件面板共用一条历史栈；选中会话仍在回复时，刷新会先确认。

Features

• Back / forward across sessions and global panels; the buttons are disabled when there is no history.
• Refresh reloads the current page rendering and reopens the panel that was open before the reload. A running session triggers a confirmation first (Esc, overlay click or Cancel dismisses it). Panel state and scroll position reset — that is the expected cost of a refresh.
• One shared stack: session switches and panel open/close are recorded in visit order, up to 60 entries, persisted in localStorage under dsh.history-nav.v1.
• Self-healing: entries whose session was archived or whose panel plugin is gone are dropped on replay instead of sticking the buttons.
• Localized: button tooltips, shortcut labels and the confirmation dialog follow the DSH locale (Chinese / English).

Placement

• Windows desktop: caption area, right of the Application / Edit menu; the same position on session pages and panel pages.
• Other platforms: the leading seat of the conversation header; global panels keep the keyboard shortcuts only.

Shortcuts

Platform	Back	Forward
Windows / Linux	Alt+←	Alt+→
macOS	⌘[	⌘]
Plain browser	Ctrl+Alt+←	Ctrl+Alt+→

Shortcuts are rebindable in Settings → Shortcuts.

Install

1. Open the client sidebar → Plugins → Add plugin.
2. Point it at this package: the local source directory, or the npm package name once published.
3. Choose Install, then Enable now; restart the client if it says the change takes effect on the next start.
4. The card must read Enabled / Mounted. The back / forward / refresh pill then appears in the title bar.

Compatibility

• Built against the DeepSeek Harness desktop client 0.2.1-rc.2. It relies on the uiWorkspace.selection projection, layout.panelInfo, the shortcut registry and the conversation header seat.
• The host half imports nothing. The browser half resolves only platform module seeds (react, @deepseek-ai/dsh-client-store).
• Client upgrades may change these contracts. When a seat or a service method is missing the plugin stays inert instead of breaking the shell; see the console for [dsh-client-ui-history-nav] warnings.

Uninstall

Disable the bundle in Plugins (or remove it from the profile's dsh.profile.bundles) and restart. History lives only in localStorage; delete dsh.history-nav.v1 to clear it.
