Summary by CodeRabbit

• Chores
  • Improved CI/CD efficiency by expanding Go dependency caching across build, test, and release workflows—caching now invalidates based on repository module lockfiles to speed repeated runs and reduce redundant dependency fetching.

Walkthrough

Added cache-dependency-path: "**/go.sum" to multiple actions/setup-go@v6 usages across GitHub Actions workflows to drive Go module cache invalidation based on go.sum changes. Changes touch build, release, and unit-test workflows.
