DeepSeek Harness Archived conversation management page

Key features

• Complete archived-session list, grouped by workspace (project) with a per-group count.
• Host half (lib/index.js) registers the /plugins/dsh-archived-chats/ routes on the DSH web server: GET /state, POST /unarchive, POST /unarchive-all, POST /delete, POST /delete-all.
• Every group can be collapsed or expanded, and the state is remembered per browser.
• Search by title, plus two filters: type (all / regular / subagent) and project.
• Unarchive a single chat or a whole project group from the group's ⋯ menu — restored chats reappear in the sidebar immediately.
