• Improved type definitions for better type safety.
• Refactoring logic for attaching the shadow root to ensure it works more reliably.
• General cleanup of redundant code and error handling improvements.
• These updates aim to make the component more maintainable and improve its usage within Vue projects.

• Improved typing: Introduces AdoptableShadowRoot and ShadowRootComponent for type safety.
• Renamed variables: teleportEl, teleportTarget, exposeData, and childPart renamed to snake_case for consistency.
• Minor cleanup: Removed unused commented-out code.

Please do not format files other than source code, as this will result in too many diffs. I suggest opening a new branch to extract modifications separately to avoid unnecessary changes.
