Detailed Description

The Fun virtual machine state.

Holds the operand stack, call frames, globals, standard output capture, runtime counters, and debugger state. Functions in this header operate on this structure; callers must ensure proper initialization with vm_init() before use and call vm_free()/vm_reset() as appropriate.
