feat(boss): add chatlist, chatmsg, and send commands

[huangsen365]

Summary

Add three new BOSS直聘 (zhipin.com) chat commands for the recruiting (Boss) side:

New Commands

Command	Description
boss/chatlist	List chat conversations with candidates (聊天列表)
boss/chatmsg	Read message history with a specific candidate (聊天消息)
boss/send	Send a text message to a candidate (发送消息)

Usage

# List recent chat conversations
opencli boss chatlist
opencli boss chatlist --page 2 --limit 10 --job_id 0

# Read chat messages (uid from chatlist)
opencli boss chatmsg --uid <encryptUid>

# Send a message
opencli boss send --uid <encryptUid> --text "你好，方便聊聊吗？"

Implementation Details

• chatlist: Calls getBossFriendListV2.json API with cookie auth, returns name, job, last message, uid, and security_id.
• chatmsg: Resolves encryptUid → numeric uid + securityId via friend list, then fetches history via historyMsg API.
• send: Uses UI automation instead of HTTP API because BOSS chat messaging is powered by MQTT protocol. The command:
  1. Opens the chat page
  2. Clicks on the target user in the sidebar
  3. Types text into the contenteditable editor (.boss-chat-editor-input)
  4. Clicks the send button (.submit)

All commands require Strategy.COOKIE with an active BOSS直聘 login in Chrome.

Testing

Tested end-to-end on macOS with Chrome browser bridge:

• ✅ chatlist returns conversations with correct fields
• ✅ chatmsg reads message history with timestamps
• ✅ send successfully delivers messages (verified via chatmsg)
