 		9dd86858e1 feat: add node budget and memory limits (#762) 
* feat: add node budget and memory limits

Implement compile-time and runtime safeguards against deeply nested expressions:

- Add MaxNodes limit to track and limit AST node count during parsing
- Move MemoryBudget from VM to Config for better configurability
- Add node creation tracking in parser to enforce node budget
- Refactor node creation to check limits before allocation
- Add RunWithConfig to VM for passing memory budget settings
- Set reasonable defaults in Config (10000 nodes, 1M memory)
- Add comprehensive tests for both node and memory limits

This prevents stack overflows from malicious or poorly written expressions
by failing fast with clear error messages during compilation or runtime.
