Implement WeChat Official Account (微信公众号) adapter

[Copilot]

Adds complete WeChat Official Account adapter following the new OneBots architecture pattern.

Implementation

Core Bot Client (src/adapters/wechat-mp/bot.ts)

• Access token management with auto-refresh (2hr expiry - 200s buffer)
• Signature verification (SHA1 hash of token + timestamp + nonce)
• XML message parsing/building via xml2js
• Customer service API: text, image, voice, video messages
• User info, follower list, media upload

Adapter (src/adapters/wechat-mp/index.ts)

• Implements all required Adapter base methods
• Webhook endpoints:
  • GET /{platform}/{account_id}/webhook - WeChat server verification
  • POST /{platform}/{account_id}/webhook - Message receiving with XML parsing
• Converts WeChat messages to CommonEvent format
• Proper log4js integration (no console.*)

Utilities (src/adapters/wechat-mp/utils.ts)

• Message segment conversion helpers
• Error formatting

Configuration

wechat-mp.my_account:
  onebot.v11:
    use_http: true
    use_ws: true
  
  appId: 'wx...'
  appSecret: '...'
  token: '...'
  encodingAESKey: ''  # optional
  encrypt: false

Dependencies

• axios - WeChat API calls
• xml2js - XML message parsing/building

Limitations

• Private messages only (WeChat MP has no group/channel concept)
• Methods for groups/channels throw appropriate errors
• Message deletion not supported (WeChat MP API limitation)

Original prompt

现在的适配器、协议、app他们的类型声明都ok了，现在，完整实现一个微信公众号的适配器
