Description: Map.Entry objects were incorrectly treated as lazy-loading candidates because they are included in COLLECTION_TYPES. This caused the debugger to display entries as 'HashMap$Node@id' instead of showing the actual key:value details inline. Map.Entry's details computation (getKey + getValue) is lightweight, so eager evaluation is safe and significantly improves UX when debugging large Maps. Fixes microsoft/vscode-java-debug#1605
