 * Creates a cursor plugin that tracks and shares cursor position and state across charts.

 * cursor data to other plugins (like tooltips) via the plugin bus system.
 *
 * **Features:**
 * - Tracks cursor position and x-series data indices
 * - Transmits cursor data via plugin bus for cross-plugin synchronization
 *
 * **Usage:**
 * ```typescript
 * import { createPluginBus } from '@dschz/solid-uplot';
 * import { cursor, type CursorPluginMessageBus } from '@dschz/solid-uplot/plugins';
 *
 * const bus = createPluginBus<CursorPluginMessageBus>();
 *
 * <SolidUplot
 *   // ... other props
 *   plugins={[cursor()]}
 *   pluginBus={bus}
 * />
 * ```
 *
 * **Plugin Bus Data:**
 * The plugin populates `bus.data.cursor` with:
 * - `sourceId`: ID of the chart that last updated the cursor
 * - `state[plotId]`: Cursor data for each chart instance
 *
 * See {@link CursorPluginMessage} for the complete data structure.
 *
 * @returns A plugin factory function that creates the cursor plugin instance
 *
 * @example
 * ```typescript
 * // Use with other plugins that depend on cursor data
 * const plugins = [
 *   cursor(),
 *   tooltip(MyTooltipComponent),
 *   focusSeries()
 * ];
 * ```
