Renders every session and its nested subagent descendants as a tree in the left sidebar, occupying the sidebar.workspaces slot, with click-through to each conversation's multi-turn history and a tree_send host tool for messaging any continuable session in the tree. Plain ESM, no build step, no runtime dependencies, and no network access.
