WeChat mini-program

Enable 构建 npm in WeChat DevTools, then import the CommonJS subpath:

const { createFatigue } = require('fatigue-kit')
const { weappAdapter } = require('fatigue-kit/adapters/weapp')
const fatigue = createFatigue({ storage: weappAdapter() })

The adapter uses synchronous wx storage. Outside WeChat, inject { client }; otherwise a missing global throws during adapter creation. Storage-operation failures are reported through onError and degrade to empty/non-durable state.
