Add tooling system for custom data processing on DB operations

[abdotop]

Implement a tooling system that enables adding data processing functions during database read/write operations.

The goal is to provide a framework to customize the processing applied to DB data using tooling interfaces. This will improve modularity and make it easier to integrate new workflows.

Use cases may include:

• Adding data validation functions during DB reads
• Applying automatic transformations during DB writes

The system should be easily extensible, allowing new tools or processing functions to be added with minimal effort.
