Pull Request Overview

This PR improves the performance of tiny YDB by refactoring task actor behavior, updating thread pool configuration and switching logic, and adding configuration options for forced foreign slots and adjacent pool management.

• Refactored THugeTaskActor in manual test to dynamically generate worker configurations
• Enhanced shared executor pool logic to utilize adjacent pools and forced foreign slots
• Updated configuration (both proto and cpp) to support new tiny YDB performance parameters
