Make FlowSynx Engine Plugin-Based for core features (e.g., Triggers, Security, databases, storage, workflow queue, logging, etc.)

[ziagham]

Describe the feature

We need to enhance the FlowSynx engine by moving towards a plugin-based architecture for core features. Instead of embedding all core functionality inside the engine, we should expose extension points where plugins can be developed, loaded, and managed dynamically.

This will ensure better extensibility, maintainability, and modularity, allowing new features to be introduced without requiring modifications to the core system.
