• Adds validation logic to properly handle computed property names in interfaces and type literals under isolated declarations
• Implements IsDefinitelyReferenceToGlobalSymbolObject method to check for valid Symbol object references
• Includes a test case demonstrating enum member usage as computed property names in interfaces

I think this diff might be bogus. The submodule’s copy of this baseline doesn‘t include declaration emit output at all, so it must have been meddled with in some way during generation.
