fix(network,std-client): make nodejs compatible

[alvrs]

NOTE: some of these fixes feel very hacky and I'm not sure we should merge this PR.

If you're a hacker at the Autonomous World hackathon and need to run the network sync in nodejs, here is how you can use this branch to make it work:

1. Clone this repository, checkout the alvrs/nodejs branch
2. Run pnpm install && pnpm build at the root
3. Run pnpm mud set-version --link <relative/path/to/mud/root> from your nodejs project root to link your project to your local MUD setup
4. Run pnpm install at your nodejs project root to install the local MUD packages

Example to changes in a project to get this running: oostvoort/imaigine#1

I wonder if there's a way to update the methods below to use an async import so we don't have to import this into browser bundles.

const indexedDB = typeof self !== 'undefined' && typeof self.indexedDB !== 'undefined'
  ? self.indexedDB
  : await import('fake-indexeddb');

closing this, as it mostly served as an example for folks urgently needing node support during the eth global hackathon. We're working on a new sync library with proper node support in #1033 (+ followup PRs)
