AI Summary: Implement a locking mechanism to prevent simultaneous execution of the draft command within a Discord channel. This is to avoid race conditions where multiple users on the same team might draft simultaneously. The solution should involve a channel-wide lock, potentially stored in a JSON file, to ensure only one draft command runs at a time per channel. The lock should be acquired before the draft process begins and released after completion or failure.
