Pull request overview

Updates Cloud Build configuration defaults for release workflows (stage/publish) by standardizing the configured machine type in both the YAML build configs and the cmrel CLI’s defaulting behavior.

Changes:

• Set options.machineType explicitly in gcb/stage/cloudbuild.yaml and gcb/publish/cloudbuild.yaml.
• Update cmrel stage / cmrel makestage default machine type string to N1_HIGHCPU_32.
• Add a cmrel publish default machine type of E2_HIGHCPU_32 when build options are missing.
