XLabs/wormhole-sc-team — reverse-engineered prompt

I want this repo turned into a working local Wormhole development setup that I can actually run and understand without already knowing the whole codebase.

Please get the monorepo into a usable state where I can start a local devnet, bring up the main services, and run a simple end to end demo that proves Wormhole is working, ideally by sending a message or moving a test asset between two supported chains that are already in this repo. Use the existing contracts, relayer, SDK, clients, and any dashboards or helper scripts that are already here instead of inventing a new structure.

Also add a short, human friendly guide in the repo root that explains what to install, the exact commands to run, what each service is for, and how I can tell the demo succeeded. If you hit setup issues, fix the obvious ones and leave it in a state where someone can clone the repo and run the demo locally with as little guesswork as possible. Check the repo docs and current Wormhole docs online if needed.
