/**
 * Local i18n loader for ep_ai_chat.
 *
 * The shared helper in ep_ai_core/i18n.js calls
 *   require.resolve(`${pluginName}/locales/${lang}.json`)
 * which only succeeds if `pluginName` is reachable from ep_ai_core's own
 * node_modules. In every real install ep_ai_core and ep_ai_chat are
 * sibling plugins, so that lookup silently fails for ep_ai_chat keys
 * and `t()` falls back to returning the literal key — meaning users
 * see strings like "ep_ai_chat.error_auth" in chat instead of the
 * translated message.
 *
 * Loading our own locale file by absolute path (rooted at this plugin's
 * directory) avoids the cross-plugin resolution mess entirely.
