Port core-py to feature parity with TypeScript

[rajkumar42]

Summary

The TypeScript core (core-ts) is currently lightweight compared to the Python core (core-py). This issue tracks porting the remaining core-py features to TypeScript to achieve feature parity.

What needs to happen

• Audit core-py's public API surface and list all modules/classes/functions
• Identify what already exists in core-ts and what's missing
• Port missing modules, prioritized by usage:
  • Agent patterns (GoalSeeking, ReAct, etc.)
  • Provider abstractions (Claude, OpenAI, Gemini)
  • Tool/function calling interface
  • Memory and context management
  • Structured output / validation
• Write TypeScript-idiomatic code (use interfaces, generics, async/await patterns)
• Add tests for each ported module
• Update README with API documentation

Reference

• Python core: https://github.com/OpenSymbolicAI/core-py
• Current TS core: this repo

Acceptance criteria

• All major core-py features have TypeScript equivalents
• Tests cover the ported functionality
• README documents the TypeScript API
