Pull Request Overview

This PR makes significant changes to HLS runtime to only keep async operations for database keys that are not affected by dirty keys. The changes implement a sophisticated asynchronous task management system using worker queues and database state preservation to improve performance and reliability.

Key changes include:

• Refactored the shake database to use a worker queue-based architecture with async task management
• Added computation to preserve only unaffected async operations when restarting builds
• Improved VFS handling with additional language kind metadata
