Summary of Changes

Hello @theguild-bot, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request constitutes a new release across several core hive-router ecosystem packages, bringing a mix of new features, critical bug fixes, and a significant breaking change. The updates aim to enhance the router's capabilities with more flexible configuration and GraphQL federation support, while also improving the robustness of error handling. Developers should note the API breaking change in hive-router-plan-executor when upgrading.

Highlights

• Breaking Change in hive-router-plan-executor: The hive-router-plan-executor package has a breaking API change, moving from version 5.0.0 to 6.0.0. This is due to the removal or renaming of the PlanExecutionError enum, which was previously publicly visible.
• New Features Across Packages: Several packages introduce new features, including support for label overrides using the @override directive and enhanced configuration options. The hive-router-config and hive-router packages now allow configuration overrides via environment variables and the ability to enable/disable GraphiQL through configuration.
• Bug Fix for Federation v1 Introspection: A bug affecting introspection for Federation v1 supergraphs has been fixed in the hive-router-query-planner and hive-router packages, improving compatibility and reliability.
• Improved Error Handling: The hive-router-plan-executor and hive-router packages have undergone refactoring to add more context to PlanExecutionError, which should aid in debugging and error resolution.
• Version Bumps: All affected packages (hive-router, hive-router-config, hive-router-plan-executor, hive-router-query-planner) have received version updates, reflecting the new features, bug fixes, and the breaking change.
