[Sync] Update project files from source repository (5c903c5)

[mrz1836]

What Changed

• Added return $? statement to the get_script_dir() function in .github/env/load-env.sh to properly propagate the exit status
• Updated GOVULNCHECK_GO_VERSION from 1.25.7 to 1.26.0 in .github/env/00-core.env
• Bumped MAGE_X_VERSION from v1.20.1 to v1.20.4 in .github/env/10-mage-x.env
• Updated MAGE_X_GOLANGCI_LINT_VERSION from v2.8.0 to v2.9.0
• Updated MAGE_X_STATICCHECK_VERSION from 2025.1.1 to 2026.1
• Updated MAGE_X_BENCHSTAT_VERSION from v0.0.0-20260112171951-5abaabe9f1bd to v0.0.0-20260211190930-8161c38c6cdc

Why It Was Necessary

• Shell function exit status propagation ensures proper error handling in environment loading scripts
• Newer Go version for govulncheck provides latest vulnerability detection capabilities
• Updated tooling versions bring bug fixes, performance improvements, and latest static analysis rules
• Keeping dependencies current reduces technical debt and ensures compatibility with modern Go ecosystem

Testing Performed

• Verified environment loading scripts execute correctly with proper exit status handling
• Confirmed all version bumps align with upstream releases and compatibility requirements
• Validated that CI workflow configurations reference the updated environment variables correctly
• Ensured no breaking changes in tool version updates that would affect existing pipelines

Impact / Risk

• Low Risk: Version updates are incremental and backwards compatible
• Shell Script Fix: The return $? addition improves error detection but doesn't change successful execution paths
• Tool Updates: Static analysis and linting tool updates may surface new warnings that need addressing in subsequent PRs
• No Breaking Changes: All updates maintain compatibility with existing workflows and configurations
