Pull Request Overview

This PR refactors the playground structure by consolidating duplicate code and reorganizing the file structure. The main objective is to merge PlaygroundGroups functionality into PlaygroundPage and extract the playground UI logic into a reusable PlaygroundWidget component.

• Extracted playground UI rendering logic into a new PlaygroundWidget component in the widgets layer
• Consolidated PlaygroundGroups component functionality into PlaygroundPage
• Created a unified usePlaygroundStore that manages both tabs and playground execution state
• Reorganized the features/playground module structure with a dedicated model subdirectory
