v1.39.0

• Summary of changes
• Breaking changes
• build: Envoy now uses Bazel 8. Because Envoy still uses WORKSPACE mode, --enableworkspace and --noenablebzlmod are required and have been added to .bazelrc; external-repository runfiles now appear directly under the runfiles root.
• build: the Intel DLB connection balancer (envoy.network.connectionbalance.dlb) is disabled for all builds due to a broken source archive.
• TLS: enforcersakeyusage is deprecated and ignored; Envoy now always enforces the certificate keyUsage extension.
