[feat] Support for Feishu and permissions

[orangle]

👍 This is a really great project. It’s much more polished and complete than several similar projects.

There are two areas that could possibly be improved. I mainly use Feishu:

1. Markdown support in Feishu cards
2. The permission settings for codex / claude-code. From what I can see, the current default seems to be --dangerously-skip-permissions. It’s fine to allow broad permissions by default, but requiring authorization for dangerous operations would be safer.

Thank you @orangle for your feedback, I have put these feature request in my todo list, and they'll be publish ASAP.

BTW, if you haven't try discord ever, I really recommend you to have a try, discord's bot ability provide much more smooth experience.
