Detailed Description

VM opcode snippet for converting a Fun Value to a JSON string.

Implements the OP_JSON_STRINGIFY instruction. Expects a boolean/integer flag indicating pretty-printing and a Value to serialize. Uses json-c to build a json_object from the Value and then renders it to a string, which is pushed back to the stack.

Build gating: compiled only when FUN_WITH_JSON is enabled. Otherwise the opcode consumes its two arguments and pushes the string "null".

Stack effect (with FUN_WITH_JSON):

Pops: pretty (bool/int), value (any)
Pushes: string (JSON representation)

Errors and edge cases:

If conversion to json_object fails, an empty string is pushed.
Pretty printing selects JSON_C_TO_STRING_PRETTY; otherwise plain output.
