renepay crash

It seems that renepay crashed on me last night. I don't think it brought the whole node down but outgoing payments were failing with "Uknown command renepay".

I'm attaching my debug log leading up to the crash:

[renepaycrash.log](https://github.com/user-attachments/files/17778718/renepaycrash.log)

I'm running CLN in a docker container from an image I built off the master branch at commit bfc00bc7f using the provided Dockerfile.
