/**
 * dsh-rewind client half: the `/rewind` command decoration, the locale
 * registration, and the session-scoped portal bridge that renders the
 * per-message ↶ rewind button (`portals.tsx` owns the button and the popover).
 *
 * The button registers through the harness's
 * `conversation.session.header.actions` slot — a typed structural registration,
 * so the plugin imports no conversation UI types and survives harness drift.
 * The command decoration (`ctx.commandUi.decorate`) makes a bare `/rewind` (or
 * its alias `/undo`) open the harness's own popupSelect instead of executing;
 * the parameterized `@<seq>` form stays the execution channel, while the
 * popover's impact and candidate reads go over the host RPC channel.
