Enforce node24 usage in GitHub actions

Add FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 env variable to build and release workflow files to force the actions runner to use node24. Update release packaging logic to support both MainApp.dist and ImageMerge.dist directories and validate the existence of necessary distribution artifacts for Windows, Linux, and macOS. This ensures builds produce consistent artifacts across platforms.
