feat(feishu): skip reply-to in DM conversations (#13211)

In DM (p2p) chats, use message.create instead of message.reply
so that bot responses don't show a 'Reply to' quote. Group chats
retain the reply-to behavior for context clarity.

The typing indicator (emoji reaction on the user's message) is
preserved in DMs — only the reply reference in sent messages is
removed.

Changes:
- Add skipReplyToInMessages param to createFeishuReplyDispatcher
- In bot.ts, set skipReplyToInMessages: !isGroup for both dispatch sites
- In reply-dispatcher.ts, use sendReplyToMessageId (undefined for DMs)
  for message sending while keeping replyToMessageId for typing indicator
