[ramfox]

upgrade to iroh v0.91.0

Very confused on this one. Looking at the output it seems fine and does the test as expected. Only diff there is on mac we have a single ipv4 addr while on the linux box we got 2 ipv4 and 1 ipv6.

However on the run itself I see this

Run ./main server --json > server_output.json &
##[debug]/bin/bash -e /Users/hetzner/actions-runner/_work/_temp/0efcd627-ea69-4552-a0e8-93873513d158.sh

Seems like we're segfaulting somewhere.

I guess given it's macOS, do the full dance locally to get it to build and then run the same locally to try and catch it?
