[yashhhguptaaa]

Issue: #614

---

Summary

Upgrade Relay from v19.0.0 to v20.1.1 across all applications and packages. This update enables future schema splitting capabilities and ensures all Relay-related packages are aligned to the same version.

Changes

Dependencies Updated

Console App (apps/console/package.json):

• react-relay: ^19.0.0 → ^20.1.1
• relay-runtime: ^19.0.0 → ^20.1.1
• relay-compiler: ^19.0.0 → ^20.1.1 (dev)
• babel-plugin-relay: ^19.0.0 → ^20.1.1 (dev)

Trust App (apps/trust/package.json):

• react-relay: ^19.0.0 → ^20.1.1
• relay-runtime: ^19.0.0 → ^20.1.1
• relay-compiler: ^19.0.0 → ^20.1.1 (dev)
• babel-plugin-relay: ^19.0.0 → ^20.1.1 (dev)

Routes Package (packages/routes/package.json):

• Updated peerDependencies to require react-relay and relay-runtime ^20.1.1

Type Definitions:

• Kept @types/react-relay (^18.2.1) and @types/relay-runtime (^19.0.1) as Relay v20 does not include built-in TypeScript definitions

Verification

• ✅ Relay compiler runs successfully for both console and trust apps
• ✅ TypeScript compilation passes without errors
• ✅ Build completes successfully for both applications
• ✅ No breaking changes detected in existing Relay code (uses modern useMutation API)

Migration Steps

1. Install dependencies:
   npm install
2. Regenerate Relay artifacts:
   npm run relay
3. Verify builds:
   npm run build

Benefits

• Enables GraphQL schema splitting into multiple files (as mentioned in Update relay to latest #614)
• Aligns all Relay packages to the same version, preventing version mismatches
• Keeps the codebase up-to-date with the latest Relay improvements and bug fixes
