Add list type, obj_free for compound types, and self-reference guard

- Implement OBJ_LIST with offset-based items array and capacity
- obj_free now releases child allocations (string buffer, list items)
- obj_print detects self-referencing lists to prevent infinite recursion
- Visualizer distinguishes freed blocks (JLANG_NOT_USE) from active ones
- JLANG_free now zeroes payload on release
