* fix(github): treat graphql_rate_limit as rate limiting
GitHub answers a spent app-installation budget with a GraphQL error carrying
code graphql_rate_limit, which neither call site recognised: the repository
query reported platform-unknown-error, and app authentication reported
Init: Authentication failure. Both readings send the user looking for a
problem that is not there, and neither is retried the way rate limiting is.
The two shapes are now recognised in one place and both call sites use it.
* fix(github): propagate GraphQL rate limits
* fix(github): preserve GraphQL response contract
