Improved usage of scratch space and enhanced error handling in the Hyperscan integration within ClickHouse.

Why it matters

This feature optimizes the management of scratch space used by Hyperscan, reducing memory overhead and improving performance. Additionally, it enhances error handling to provide more robust and reliable pattern matching operations, which is critical for users relying on Hyperscan for efficient string search queries.

How to use it

The improvements are internal to the Hyperscan integration and require no changes to user queries or configurations. Users will benefit automatically from better performance and stability when executing pattern matching functions that utilize Hyperscan.
