* 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.
