Pull Request Overview

This PR migrates the Storybook addon from CommonJS/dual-format to ESM-only, targeting Storybook version 10. The migration removes CommonJS support entirely and updates dependencies to use newer Storybook versions.

• Converts the build configuration to output only ESM format
• Updates module resolution to use ESM imports and removes CommonJS require statements
• Upgrades Storybook dependencies from v9 to v10 and consolidates them at the workspace level
