Émile Ré 4433e0a9d0 Restore GraphQL schema merge for Relay query text
relay-compiler requires a single schema file: a directory is rejected
and schemaExtensions marks fields as client-only, so it emitted
text: null and the console posted query: null, getting a 400 on every
operation.

Restore the merge step (contrib/merge-graphql-schema.sh, the
RELAY_SCHEMAS make rules, and the gitignore entry) and point each
relay.config.json project back at the merged schema.graphql. The IDE
graphql-config removal and npm-script cleanup are unrelated and stay.

# Merge split GraphQL schema files into a single file for Relay.
# Strips "type Mutation" and "extend type Mutation { ... }" blocks,
# then appends a single "type Mutation { ... }" with all collected fields.
