CLN xpay testing

[Sjors]

CLN just added a new plugin to improve payment routing, which can be enabled by setting xpay-handle-pay=true. This slightly changes the pay command output, so needs to be tested.

https://github.com/ElementsProject/lightning/blob/master/CHANGELOG.md#experimental

I upgraded CLN on my server to v24.11 and tested against Zeus 0.9.3 TestFlight build 104, connected using clnrest.

A generated a simple bolt11 invoice in Phoenix.

It worked!

I didn't test payment failure or any edge cases though.

That's great news. Looking forward to greater payment success rates w CLN

Unfortunately 24.11.1 appears to have broken using xpay-handle-pay with Zeus :/

Might not require action on our end. This PR appears to address it ElementsProject/lightning#7958

Ah awesome, I hope it does!!

btw, everything works as long as you use CLNRest and not C-Lightning-Rest, the latter is the deprecated version.
