Description

This PR moves what was the @graphprotocol/hypergraph-cli cli tool and UI to be published as part of @graphprotocol/hypergraph.

This solves a few issues that were present in typesync v1:

• needed to install the package globally, which came with a set of issues across npm/pnpm/yarn, etc
• typesync spanned multiple apps/schemas and stored the app data in sqlite.
  • this made the experience feel very disconnected from the apps that we being built
• typesync was responsible for code generation of the entire app, which was really problematic

The typesync v2 approach solves these issues by:

• bundling the cli tool and typesync studio UI as part of the @graphprotocol/hypergraph package that is installed as a dep in the hypergraph enabled app -> no need for an extra install, especially a global one
• the typesync ui focuses only on the schema in the repo where it is ran -> no need to store multiple apps/schemas in sqlite
• typesync is now only responsible for reading/updating the schema and mapping files

Once the @graphprotocol/hypergraph dep is installed, it can be ran with hg typesync --open
