chore: release version v0.35.6

We use timeout controllers to ensure we're not dialling peers forever but we can end up registering lots of listeners for the `abort` event when peers have a lot of addresses.

In node this means we see an unhelpful `MaxListenersExceededWarning` in the console warning of a potential memory leak.

Increase the max number of listeners on the signal to silence the warning.
