Research direction

Examine the VS Code source code for extension contribution point schemas (likely in `src/vs/platform/extensions/common/` or `extensions/`). Look for how intellisense is provided for `contributes.menus` groups. The issue requests that the 'group' property provide completions from valid groups defined by other extensions or VS Code itself. Check existing schema definitions and completions providers. Consider using the extension manifest schema or providing a dynamic provider that reads registered groups from extensions. No linked PRs or maintainer comments to follow.
