[Sync] Update project files from source repository (58a7526)

[mrz1836]

What Changed

• Updated MAGE_X_VERSION from v1.23.0 to v1.24.0
• Added new configuration variable MAGE_X_AUTO_DISCOVER_BUILD_TAGS_COMBINE=true
• Added comment documentation explaining the new variable: "Run all discovered tags in a single test pass (fast). Set to false in a project env file to fall back to one separate pass per tag."

Why It Was Necessary

• Upgrade to the latest mage-x version to incorporate new features and fixes
• Introduce the ability to run auto-discovered build tags in a single combined test pass for improved performance
• Provide flexibility to override the combined test behavior at the project level when needed

Testing Performed

• Verify that mage-x v1.24.0 downloads and initializes correctly
• Test that build tag auto-discovery runs in combined mode by default
• Validate that the new configuration variable can be overridden in project-specific env files

Impact / Risk

• Low Risk: Configuration change with sensible defaults that improve test execution speed
• Performance Improvement: Combined test passes should reduce overall CI/test execution time
• Backward Compatibility: Existing behavior can be restored by setting MAGE_X_AUTO_DISCOVER_BUILD_TAGS_COMBINE=false
