/**
 * Refined jQuery plugin adapter for the Nepali date picker family.
 *
 * Fixes over the original
 * ────────────────────────
 * 1. getValue returns first-element value  – jQuery convention; the original
 *    iterated every element and returned the last one.
 *
 * 2. Full method surface  – added setValue, getState, and onChange to the
 *    PluginMethod union; they exist on PickerInstance but were unreachable.
 *
 * 3. No-op container re-read removed  – DateRangePicker was spreading options
 *    and then re-assigning container from the same object (a no-op).
 *
 * 4. Deferred auto-init  – instead of running once at import time (which fails
 *    if jQuery loads after this module), we also listen for a custom
 *    'jquery:ready' hook and for the common pattern of jQuery being assigned
 *    to window after DOMContentLoaded.
 *
 * 5. Typed generics  – PickerInstance is parameterised with the correct result
 *    types instead of unknown.
 *
 * Usage
 * ─────
 * // Init
 * $('#from').nepaliDateRangePicker({ mode: 'BS', numberOfMonths: 2 });
 *
 * // Method calls
 * $('#from').nepaliDateRangePicker('show');
 * $('#from').nepaliDateRangePicker('setValue', undefined, { start: d1, end: d2 });
 * const val = $('#from').nepaliDateRangePicker('getValue');   // first element
 * $('#from').nepaliDateRangePicker('option', 'minDate', new Date());
 * $('#from').nepaliDateRangePicker('destroy');
