Smoldot - crash strategy

[wirednkod]

We need to have a strategy when a smoldot crash happens.
Probably, when this occurs, we should disconnect the apps from the chain, inform the UI (emit?) of the App and/or the extension and re-start smoldot.

As a heads up, this can be done by catching a CrashError when calling any of the methods of smoldot:
https://github.com/paritytech/smoldot/blob/409ea559fa7fddfccd79c4f000def8f0e81bd350/bin/wasm-node/javascript/src/index.d.ts#L43.

I would suggest doing all of this in index.ts.
