This PR adds support for Substrate Metadata V16. The main structure and conversion logic are in place, so the core of the feature is done.

There are still a few things to clean up and polish on the edges, so I’m opening this as a Draft to track progress and get early feedback.

The implementation is mostly done, except for the update of the metadata files for Polkadot, Kusama, AssetHub, and Substrate. These will be added in a follow up PR once they're available on their respective chains.

Since MetadataV16 hasn't been finalized yet, I'm planning to keep this PR as a draft for now, as things are still subject to change.

That said, feel free to take a look and share any early feedback in the meantime 🙏🏻
