Always Generate Graphql Types

• The GraphQL Code Generator is used to auto-generate the types for both API and client
• It also generates hooks and code for the UI
• Any time we edit the GraphQL schema, we must run yarn run generate to update the generated types.
• We never manually edit the types/graphql.ts file in the server
• We never manually edit the src/generated/graphql.tsx file on the UI

Important: Do not change codegen configuration

• Do not edit codegen.yml or environment variables to “make codegen work”. Use the existing yarn generate scripts as-is in each project:
  • UI: yarn --cwd proofofcombat-ui generate
  • Server: yarn --cwd proofofcombat-server generate
• If codegen fails in a sandbox due to environment quirks (network, CPU detection, or sandboxed system calls), run the same yarn generate locally where it succeeds rather than changing repo config.
• Never switch schema sources or hardcode endpoints in the repo when running codegen.

See the "Never use graphql tag in the UI project" rule for details on the UI's auto generated hooks.
