dsh-session-unarchive

DSH 2026-10-01 added a session archiving feature, but it is hidden by default in the Web interface, preventing users from viewing or restoring archived sessions. The `dsh-session-unarchive` plugin resolves this as a pure Cordis plugin without requiring modifications to the DSH installation directory. It adds an “Archived” button to the sidebar, displays a list of archived sessions, supports title filtering and one-click restoration, and offers both Chinese and English interfaces. Users must install it via dependency injection; it no longer relies on file patching.
