Set up modular symbolic logic engine structure

[Steake]

Establish the project's modular architecture for the symbolic logic engine.

• Define clear modules for symbolic reasoning, multi-strategy inference, and advanced logic handling (resolution, modal logic, SMT, constraint logic programming, analogical reasoning).
• Ensure explicit symbolic reasoning steps and transparent inference pathways are documented in each module.
• Enable composability: Make each logic module independently testable, reusable, and compatible with the GödelOS knowledge graph.
• Document reasoning chains and module interconnections for clarity and explainability.

This issue reflects GödelOS's commitment to modular, transparent, and composable symbolic cognition. Each step should encourage explicit logic, traceable inference, and explainable structure.
