Design and implement a udf framework for pre-aggregation

**Additional context**
advanced long-time window feature

The issue requests a pre-aggregation framework for UDFs to support advanced long-time window features. Start by examining the existing UDF and window function implementations in the codebase, likely in src/. Look for aggregation logic and windowed query processing. 'Done' means a designed and implemented framework that integrates with the existing feature computation pipeline.
