What Changed

• Added a new github-token input parameter to .github/actions/setup-go-with-cache/action.yml for private module authentication
• Added a new github-token input parameter to .github/actions/warm-cache/action.yml for private module authentication
• Implemented a new step "🔐 Configure private module authentication" in the setup-go-with-cache action that conditionally runs when both GOPRIVATE is set and github-token is provided
• The authentication step configures git to use the token via git config --global url."https://x-access-token:${PRIVATE_MODULE_TOKEN}@github.com/" and sets GONOSUMDB to match GOPRIVATE if not already set

Why It Was Necessary

• Enable GitHub Actions workflows to authenticate and download private Go modules during builds and tests
• Support repositories that depend on internal or private Go modules that require authentication to access
• Provide a secure way to configure git credentials using GitHub tokens without hardcoding authentication details

Testing Performed

• Verified the action accepts the new github-token input parameter with appropriate default values
• Confirmed the authentication step only executes when both conditions are met (GOPRIVATE set and token provided)
• Validated that the git configuration correctly formats the token for HTTPS URL authentication

Impact / Risk

• Breaking Change: None - the new input parameter is optional with an empty string default
• Security: Low risk - token is passed as an environment variable and only used when explicitly provided
• Compatibility: Existing workflows continue to function unchanged; new functionality is opt-in only
