Module unwrap_cast 

Unwrap casts in binary comparisons for physical expressions

This module provides optimization for physical expressions similar to the logical optimizer’s unwrap_cast module. It attempts to remove casts from comparisons to literals by applying the casts to the literals if possible.

The optimization improves performance by:

1. Reducing runtime cast operations on column data
2. Enabling better predicate pushdown opportunities
3. Optimizing filter expressions in physical plans

Example

Physical expression: cast(column as INT64) > INT64(10) Optimized to: column > INT32(10) (assuming column is INT32)
