Code Review

This pull request introduces several major updates across multiple Google Cloud Java libraries. In google-auth-library-java, it implements per-cycle mTLS certificate pinning, 401 recovery, and actor token delegation for Workload Identity Federation. In java-bigquery-jdbc, it adds support for discovering Property Graphs and related metadata in DatabaseMetaData methods when EnableGraphMetadata is enabled. In java-spanner, it refactors streaming result sets and transaction handling to improve robustness around inlined BeginTransaction and stream retries. A review comment identifies a regression in BigQueryDatabaseMetaData.java where the refactored getColumnTypeInfoForTypeKind method fails to handle the ARRAY type kind, which could cause procedure arguments of type ARRAY to be incorrectly mapped to STRING.
