Module execution 

Execution engine for running processing pipelines with configurable parallelism.

This module sits “above” crate::processing and provides:

• Parallel (chunked) execution for filter/map
• Resource limits / throttling (e.g., in-flight chunks)
• Real-time metrics + observer hooks for monitoring
