/**
 * Per-button label sync hook for the Inbox channel sidebar.
 *
 * Mirrors the Email channel's `useNodeAttributes` sync pattern but handles the
 * two node shapes that appear in Inbox:
 *   - `buttonRow` (atom): 2 buttons merged into 1 node with button1Label/button2Label attrs
 *   - `button` (inline-content): standalone button nodes with a `label` attr
 *
 * Editor → sidebar: subscribes to `editor.on("update")`, reads the label from the
 * correct node/attribute, calls `form.setValue` (same as `useNodeAttributes`).
 *
 * Sidebar → editor: returns `updateLabel(newLabel)` that immediately updates the
 * editor via `setNodeMarkup` (buttonRow) or `updateButtonLabelAndContent` (button).
