Refactor the `process_message` function in `bot.py` to improve performance and handle longer messages. The function now appends extra characters to the base message to ensure it is always 4000 characters long. This change improves the processing of messages and prevents truncation.
In `messageCreate.js`, split the output into chunks of 2000 characters using the `splitMessage` function. This allows sending each part as a separate message, ensuring that the output is not cut off.
