v3.3.0rc0

Release candidate GraphQL-core v3.3.0rc0, based on GraphQL.js v17.0.0rc0.

This release candidate supports Python 3.10 to 3.14.

There are no breaking changes after the last beta version 3.3.0b2.

Notable changes:

• Improved validation of the @defer and @stream directives. The DeferStreamDirectiveOnRootField rule now also forbids these directives on fragments that are spread on abstract types at a mutation or subscription root, and the DeferStreamDirectiveOnValidOperations rule now tracks fragments more thoroughly when detecting @defer/@stream on subscription root selections. As a result, some documents that were previously accepted may now be correctly reported as invalid.
