[mrz1836]

What Changed

• Updated MAGE_X_VERSION from v1.15.5 to v1.17.4 in .github/.env.base
• Updated MAGE_X_GORELEASER_VERSION from v2.13.2 to v2.13.3
• Updated MAGE_X_BENCHSTAT_VERSION from v0.0.0-20251208221838-04cf7a2dca90 to v0.0.0-20260112171951-5abaabe9f1bd
• Added new configuration variable MAGE_X_MAGE_VERSION=v1.15.0
• Updated GO_PRE_COMMIT_VERSION from v1.4.6 to v1.5.1
• Added new composite action .github/actions/setup-mage/action.yml for installing and caching the mage binary
• Modified .github/workflows/fortress-test-matrix.yml to incorporate the new setup-mage action

Why It Was Necessary

• Keeping MAGE-X tooling up to date ensures access to latest features, bug fixes, and security patches
• The new setup-mage composite action provides efficient binary caching and PATH management to reduce workflow execution time
• Standardizing mage installation across workflows improves consistency and reduces duplication

Testing Performed

• Verify CI workflows execute successfully with updated tool versions
• Validate that the setup-mage action properly installs and caches the mage binary
• Confirm PATH management allows immediate mage binary availability in subsequent workflow steps
• Test cache hit/miss scenarios to ensure proper installation behavior

Impact / Risk

• Breaking Change: None - these are internal tooling updates
• Performance: Improved workflow execution time through binary caching in the new setup-mage action
• Risk: Low - tool version updates are incremental and the new action provides isolated functionality
• Migration: Automatic - existing workflows will use updated tool versions on next run
