Pull request overview

This PR appears to finalize migrating the packages/indexer package into the Yarn v3 monorepo (removing its pnpm lockfile) and updates the Envio subgraph reader to enrich hub deposit/invoice parsing with HubIntent status fetched from Envio.

Changes:

• Add packages/indexer as a Yarn workspace and update dependency lockfiles accordingly.
• Update the indexer README instructions from pnpm to yarn, and correct the chain name to “Unichain”.
• Update EnvioReader to fetch HubIntents for deposits/invoices and propagate intent status into parsed results.
