/**
 * Collapses the primary sidebar on mount for focused full-page forms / wizards.
 * Restores previous primary state on unmount.
 *
 * Focus workflow routes hide both primary sidebar and secondary panel — see
 * `lib/focus-workflow.ts` + `SecondaryPanelProvider`.
 *
 * Both transitions pass `{ persist: false }` so the visual collapse never
 * overwrites the user's saved sidebar preference (the `sidebar_state_v2`
 * cookie). Only an explicit toggle (⌘B / sidebar button) persists.
