An EVM compatible Substrate chain, powered by StorageHub and secured by EigenLayer
728c320926
In this PR: 1. Add [Polkadot API](https://papi.how/) support to `test/` directory (i.e. the e2e CLI and testing framework) to be able to interact with the Substrate chain. 1. This allows typed interactions with transactions, constants, storage, runtime APIs, and non-typed interaction with RPC methods. 2. Types are autogenerated when running `bun i`, from the `datahaven.scale` file that is part of this repo's version control. 2. Add new utilities file to `papi` related functionalities. For the time being, generating a new signer from a private key. 3. ~Add a new step to the CLI that sends a transaction to the DataHaven network. _*THIS SHOULD BE REMOVED SOON, IT'S JUST FOR TESTING PURPOSES*_~ 1. Both steps that send test transactions have been removed from the CLI, for convenience and being error prone. Their scripts remain usable for testing purposes if needed. 4. Removes the `apis.rs` files from the runtime definitions. Having them in a separate file meant that the runtime was not including the Runtime APIs in the metadata blob, preventing `papi` from creating types from it. This change can be reapplied after upgrading to `polkadot-sdk` `stable-2503`. More info [here](https://github.com/paritytech/polkadot-sdk/issues/6659). 5. Add script to re-generate types, and corresponding docs. 6. Makes logger synchronous to avoid prints happening before logs. |

CI
Using the act binary, you can run GitHub Actions locally.
For example, to run the entire e2e workflow:
act -W .github/workflows/e2e.yml -s GITHUB_TOKEN="$(gh auth token)"
Which results in:
INFO[0000] Using docker host 'unix:///var/run/docker.sock', and daemon socket 'unix:///var/run/docker.sock'
INFO[0000] Start server on http://192.168.1.97:34567
