Plugin

Keeps running, finished-but-unopened and currently open sessions pinned above the workspace groups in the DSH Web sidebar, and lets any session or workspace be pinned there from its own "..." menu.

Adds a Workspaces / Recent-sessions switcher above the sidebar list, with a pinned-sessions group, a per-row menu (pin/unpin, copy session id), title filtering, and browser-local pin storage with a one-shot migration from dsh-plugin-pin-session.

Pinned-sessions block for the DeepSeek Harness sidebar: a collapsible pinned panel above the Settings row, hover pin buttons on session rows and a session-header toggle. Pins live in the plugin's own settings namespace and are migrated once from dsh-sessi

A pinned-sessions group in the sidebar, above the workspace list: every pinned session across all workspaces in one collapsible, searchable list, with click-to-open and a hover-revealed unpin button.
