Add vscode-rojo submodule and update schemas for Atlas rebranding

- Added the vscode-rojo submodule to the project, linking to the UserGeneratedLLC repository.
- Created a new plan for syncing vscode-rojo schemas, detailing updates to project, meta, and model schemas to align with the Rojo fork and rebrand as "Atlas".
- Enhanced the Theme and DomLabel components to support subtree highlighting, improving user interaction in the PatchVisualizer.
- Updated the PatchVisualizer to manage subtree highlight state and ancestor IDs for better visual feedback during selection.
