Feishu Reaction Tool

Single tool feishu_reaction for adding, removing, and listing emoji reactions on Feishu messages.

Workflow: Reacting to Previous Messages

To react to a message other than the current one, first use feishu_message with action: "list" to fetch recent messages and find the target message_id, then use feishu_reaction with that message_id.
