What Changed

• Updated GOVULNCHECK_GO_VERSION from 1.26.1 to 1.26.2 in .github/env/00-core.env
• Updated GO_COVERAGE_VERSION from v1.3.7 to v1.3.8 in .github/env/10-coverage.env

Why It Was Necessary

• Keeps the govulncheck tool aligned with the latest Go patch release for improved vulnerability detection
• Updates the Go coverage tooling to the latest version for potential bug fixes and improvements
• Ensures CI/CD pipeline uses current stable versions of development tools

Testing Performed

• Version bump changes are declarative configuration updates that will be validated when CI workflows execute
• The updated tools will be automatically downloaded and used by GitHub Actions during next workflow runs
• No direct functional testing required as these are dependency version declarations

Impact / Risk

• Breaking Change: None - patch version updates maintain backward compatibility
• Risk: Very low - minor version bumps for development tooling used in CI environment only
• Performance: No impact expected - versions are close increments with stability improvements
