/**
 * Sidebar entry injection — package-specific wiring over the shared core.
 *
 * dsh's sidebar shell exposes no slot an external plugin can register into
 * (`sidebar.workspaces` / `sidebar.settings` are single-occupant and already
 * taken), so the entry row is injected between the shell's New Session button
 * and the workspace browser. The DOM injection / self-healing / idempotency
 * logic lives exactly once in shared/client/sidebar-entry-core.ts (synced
 * copy); this wrapper supplies the task-board icon, copy, CSS module, and the
 * board toggle. The row is plain DOM (no React tree); the board view it
 * toggles is a separate React root mounted in the center column
 * (see board-mount.ts).
