/**
 * I18nRegistry — shared locale-aware message registry for all farm plugins.
 *
 * Plugins register their message bundles (per locale) at startup.
 * The registry resolves messages by plugin name + key + current locale.
 *
 * Usage:
 *   import { i18n } from 'plugin-common-lib/i18n'
 *   import messages from './messages.js'
 *
 *   i18n.register('struct', messages)
 *   i18n.setLocale('zh')
 *   i18n.msg('struct', 'doubleFree', '0x1A3F')
 *   // → "在指针 0x1A3F 处检测到重复释放。该块已被释放。"
