Pull Request Overview

This PR updates the memory control framework for pipes by introducing a new floating memory proportion configuration and refactoring memory calculations to distinguish between total non-floating and floating memory. The key changes include:

• Adding a new configuration property (pipeTotalFloatingMemoryProportion) and its corresponding getter/setter methods.
• Updating memory calculations in multiple components (e.g., PipeMemoryManager, subscription caches, extractors, and task agents) to use non-floating memory metrics.
• Renaming methods and variables for consistency (e.g., tsfile → tsFile).
